I *almost* agree with you Tony - except that with any 250 performance
depends a lot on your body weight.
My wife started on a CB-250, and while I couldn't get it over 105kms, she
routinely got it up to 130+. (For reference I weight 85kgs, she weighs 50
kgs).
Manning
Horseshit.
I don't know how relevant this is, but I ride a ZZR250, and it seems to
handle the freeway quite fine, I have done quite a few 100km trips, and I
have managed to get her up to 150km/h, being new to this, I really don't
wanna try any higher... :p
Tina
There are better 250s for that, ain't no doubt.
On the other hand, that bike will certainly manage 100 for 40km (as
long as you are a reasonbly sized bloke) without drama.
What it won't managed is much more than that, or much in the way of
passing manouveres.
All depends on your temprement and money requirements I suppose. I rode
a 250 MZ all over eastern Oz, a machine with a top speed of maybe 120kmh on
the flat in a dead calm with plenty of runup, but usually it was OK at
100 and struggling at 110. Yes being able to go faster was nice,
especially when stuck behind a truck in the wet at 90/100, but it wasn't
required.
If you are someone who can cope with not being the fastest out there,
who won't feel trapped and scared if you can't pass other vehicles, and
you want a bike with excellent fuel economy and very reliable, then a
CB250 will be fine.
If you prefer to be able to pass everyone, like to carve traffic, can't
stand not being first, you will find the CB250 too slow.
You may want to enquire at any bike hire places, some of the have that
model in the fleet, you could test it yourself. If not, then do your
damndest to get a test ride and determine for yourself how it feels to
ride at the speeds you expect.

Dunno about the CB250, but if you were to go the VTR250 (very nice looking
thing) or CBR250RR (which is what I've got) I think you'll find yourself
having more of a power reserve. Mine is good for 190 on the island. This is
indicated, real spead probably 170 or so - haven't had the chance to
calibrate with GPS at that speed.
I'm just shy of 1.90m tall & some 90-95kg with all my gear on. I think it
helps being flexible for longer trips, however 40Ks should not be a problem
at all.

Both single-cylinder soft trailbikes. Criticising their

Only because CB750's of that vintage rev to 9,000rpm (if
they're lucky).

From memory, a BabyBlade's geared for ~10kph/1,000rpm in
top gear. They redline at 18,500rpm, meaning 110kph works
out as ~11,000rpm, or just over 60% of redline. How can
that be thought of as high engine speed?

Or it could be that, as an ag bike, it just has a very low
revlimit.

So what's your advice? That this guy, who's contemplating a
common-as-muck 250 runabout should instead look into buying
a 20-year-old mastodon for similar moner, or a 1000cc v-twin
soft sportbike for four times the money?

You make the point that there may be budget bikes beter
suited to freeway commuting than a CB250 by a very strange
route...
...for my money, I'd say that, if the choice is between a
newish CB250 or an old large-capacity UJM for similar money,
go the CB250 and forego the decaying carb manifolds, dying
CDI boxes, loose bearings and all other age-related joys
ownership of such a bike brings, while being secure in the
knowledge that, should anything go wrong, it won't be
anything complicated thanks to the bike being as bog-basic
as it is, and wreckers will be able to help out with
bountiful 2ndhand parts that don't necessarily predate both
the Gulf Wars.
If the money and the license conditions (the morning commute
isn't much of a place to play renegades) are there, then I'd
even advise something like what I just got for commuting;
a middle-aged 600 that's had an easy life. Properly
maintained, they're a lot tougher than people give them
credit for and spares for them are the most plentiful of all.
Well it's not the first bike I would choose to do regular freeway runs on, but
it should sit happily at a 100-110 day in and day out without too much issue.
The reason it wouldn't be my first choice is unless you're very light it will be
at the top end of it's rev range, if you choose something with a bit more go it
may be a bit less like hard work, you'll not find yourself dropping back to 80
when you hit a steep hill, that sort of thing, not struggling to overtake a car
doing 95 etc.
Consider VTR, Spada, GPX, ZZR, across, Balius, bandit, zeal as alternates that
will sustain 140 happily and hence will be less stressed at maintaining 100.
Noting that the twins (VTR, spada, GPX, ZZR) will probably be slightly cheaper
to maintain.
JL
I can't see that being a problem.
> I've asked a few people about the bike and they seem to think that

eg: you'd get bored if you were riding around Australia entirely
on Highway 1. 80km a day is _not_ "long distances". 800km a day
and you'd be starting to go beyond the design of the CB250,
but even then I doubt the bike would suffer too badly.

The only problem with the CB250 is you might get bored of it
sooner than a more exciting 250 such as the Spada that IK is
trying to sell :-)

And I disagree. Jeanette had a CB250 and we regularly used it for lengthy freeway runs. Sure it had
to work hard in a headwind to stay around the 100 km/h mark, but it soldiered on quite happily. On
low wind days it would cruise at 110+ km/h. An excellent commuter that we used to great affect in
that capacity.
And dead easy to work on should anything need replacing or repairing.

Strange that you'd choose to give advice on the suitability of a CB250 by
giving information on a whole bunch of bikes which are really nothing like a
CB250. Cat did lots of freeway commuting on her CB250 I think... you have any
advice Cat?

... eg: you'll have to downshift to go up hills? Probably. But
freeway touring it'll go okay in top, I imagine, and the gearing
won't be effected by the riders weight ...
The humble CB250 is also a twin. But agree, unless you're 70 kgs or less it
will struggle to get much over 110.

Damn staright. I'd blow up. I read that they aren't supposed to go above

Now a serious answer!
I rode the freeway so long on my 250, I put Highway pegs on it for improved
comfort.
Sounds like the opinion you have been given are shite, and so are the
salespersons. Fuck them off with a big stick, and then snap of a cable on
their front doorstep.
Hammo
Top speed is based on maximum engine power, not vehicle mass.
The only difference a heavier rider could possibly make is to increase wind
drag slightly.
40 kms at 100 is only 24 minutes. Hardly a long period. My neighbour
rode to work every day down the Freeway on his Dream 305. A CB 250
will have no problems. Go for it.

The CB250 is a great little bike but if you're doing regular freeway runs as
you say and you weigh 80kg or more you'de probably be more comfortable on
something with a little more go. Yeah, they DO go the speed, but might be a
different story when you want to overtake or a huge hill. Being a 250 it'l
depend on the wind speed, temperature, when you last brushed your teeth etc
as to whether or not it'l cruise happily at 110.

Cam

I used to ride a Kawasaki GPZ250 to work every day, but it was only
about 10 minutes on the freeway, no problems.
The CB250 will do it without any problems, but if I was going to do this
commute long term, it's not the bike I would select.
Being a light 'naked' bike you are exposed to the wind and weather to
much. After a while it gets annoying being buffeted around and you'll
ponder how much better it would be, to have more weight, and maybe more
protection.
I would suggest a 600 cc bike with a fairing for this commute, if you
plan to keep this job long term, because after a while commuting this
distance on a 250 will become a chore and you'll probably regret it.

I think it is more, go and check the real world instead of physics
theory. I think I know where you are coming from, but real world says
"no" to that.
Nice try Sharks but if it's at the top end of it's rev range to sit at 100 *in
top* then downshifting at the bottom of the hill isn't going to be pretty (not
even CBs will put up with a lot of that :-). And while the gearing is unaffected
by the rider's weight, the maximum speed the vehicle will pull against a certain
gearing ratio is impacted by the riders weight (ie if you're a fat fuck it aint
going to keep that 100K happening as soon as even the slightest rise appears on
the horizon - whereas if you're Cat, the bike won't even know you're there)
JL
Blimey, what is this ? Pick on JL night ? :-)
I was referring to the twins in the list of alternates as opposed to the fours

JL
ROTFLMAO !!!
You've obviously never ridden a low HP bike then.
JL
Hint: there's a correlation between the highest gearing you can pull, mass being
shifted and HP/torque
If you are going to get a CB250 for freeway use , then get bigger carby jets
for it.
Replace the #35 slow jet with a #38 and replace #110 main jet with a #115.
The jets cost $28 for the two and 1 hours labour at a bike shop.
I had my CB jets replaced with the bigger jets and I have found that the
bike runs a lot better at speeds faster than 60 kph and especially on the
freeway @ 80 kph - 100 kph.
The fuel usage is only about 2 - 5 Km / litre less than with the stock
standard jets.
Before I was getting 28 - 32 Km /litre using the stock jets and with the
bigger jets I am getting 25 - 28 Km/litre , with a lot of freeway use , you
will probably get 28km /litre.

CB250? hell i guess it'd do the job quite well, but as Zeb says, you certainly will *not* be
the fastest thing on the road.
Also at highway speeds you'd be up in the rev range and im not sure if it's just me or not,
but even while taking a blatt around on a CB250 on my P's test I found the power to be
in the middle of the revs, and it quickly turned into vibration at anything about 6k RPM
(im gathering that'd be about 90ish km/h in top gear).
At the end of the course i was *very* glad to go home to my EL250 which felt a HELL
of a lot smoother (vibration and power deliver wise) and balanced (ok ok so it had a
few more HP too which came in up to a 14k or so redline).
But if you like the feel of it, and dont have any niggling feelings about its handling, by
all means get one. But in all honestly the GPX's, VTR's and Spada's these guys on this
NG are selling would *certainly* be able to do what you want (and possibly have a little
something in reserve "in case" you ever needed to get around that semi going up a hill.

Precisely, why else do you think lams is based on a "power to weight ratio" bugger ?
Also why the hell else would a R65 Bimmer be on the list? got a shedload of power,
but as heavy as a sherman tank. And by that logic a WRX blinged up to the
max should whoop the butts off anyone with a 'busa if we followed your logic.
Sure wind resistance has an effect on things, but the real issue is something to do
with propelling force, inertia, momentum & weight.
Actually rode the bike from Melbourne to the OX and then to the Queensland
border and back, bike didn't have a problem I personally wouldn't get
anything that struggles at 110, sometime you want to go for a cruise and
not having to hold your bike flat makes it more enjoyable. Also to avoid an
accident its good to have another option than breaks.

Ummm, you need to have a conversation with the Japanese guy on a CT90

Ummm, if you gear a CB250 higher (so it has less revs at 100 km/h) it
probably will no longer be capable of doing 100 km/h.

The longest trip I've done on a 250 was Canberra - Puckapunyal on the GPX250 (about 650km). Except for a short stretch
on the Barton Highway at the beginning, the whole trip was on the Hume Highway at or exceeding the 110km/h limit. At no
point did I have any trouble holding that speed, nor with finding a bit extra when the need to overtake arose.
Admittedly, the GPX250 has a bit more go than a CB250, but I think it will do just fine for a 40km trip! And if you
still have any doubts, ask BTH about his regular epic journeys on a GPX250 (Canberra - Ayers Rock on one occasion, and a
complete circuit of Australia on another).

Undoubtedly.

do a quick search on power to weight ratio's.
yes I agree, a fatter person would cause more wind resistance..
my vtr250 handled touring quite well, I did many 1000k+ trips on it and it
didn't complain one bit.. except when its 2 (180kg) up trying to get more
than 120-130 out of it..

I'll agree with your second sentence, but not your first. A CB250
would be perfectly adequate for a 40km highway commute, although how
fast it will get there is very dependent on the rider's weight. I
hear that Postman Pat rode his to the Capital rally a few days ago?
But then I'm planning to borrow my dad's CT90 for the trip to
Wintersun this year, so what would I know? ;-)

That's OK, I doubt you had much beyond 150kph on a ZZR250 anyway! ;-)

Breaking is always bad. Mind you, correct use of your brakes is often
a better solution than trying to "power your way out of trouble".

Absolute twaddle.
Get a bikini screen for it to streamline the airflow and you'll get it
up to 110 without the buffetting.
I owned a CD250u (same engine as the cb250 but with twin carbies)
I weigh 85 kilos and regularly got it to 130 kmh.

Well, I'm not sure I've ever done more than 6 or 7 hours continuous at
100kmh+ on the Spada (less then 2 hours if you don't ignore petrol
stops), and I've rarely done more than 3 1000km days in a row...
It all depends on what you mean by "long periods"...

Nick 'Sharkey' Moore | Everyone complains about the laws of physics
<sha...@zoic.org> | but nobody ever does anything about them!
I own a CB250 and occasionally ride it on the freeway (Syd to
wollongong) It is very happy at 80-90 will do 100klm/h and has got up
to 110Klm. Steep hills see it drop back to 80 in 4th gear. Its revving
fairly hard (and will happily do so all day) at these speeds. Its not
as smooth as a 4cyl but not unacceptably coarse. There is some
vibration from the engine at these speeds. I get tingly hands. having
never been on a big slow revving bike, I dont know if these are less
tiring.
It has no fairing and a very upright (and exposed to the wind) seated
position. This is not a problem in summer but you get very cold and
miserable in winter. The tank is low, and thus funnels cold air up
between yor legs and into your crotch hence frozen genetalia.
Around town, it is an excellent bike, very maneurble but for your free
way intentions including winter and bad weather, a comfortable faired
bike may be better. As I said, I dont know if bigger engine is better.
This sounds very interesting, where does one obtain these jets from?
and who do you reccomend to do the work?

How long does it take to change gears on a CBR250 then?
BTH
Some handlebar end weights will reduce the "tingly" vibration quite a bit.
They're usually quite cheap from wreckers, and easily mounted (you don't
need threaded ends on your handlebars to fit them).
BTH
Shouldn't that be "if you're *heavy* it just won't be able to pull up to the
top end of the rev range"? ;-)
BTH
(Just pleased that someone else is getting picked on for a change!)
Oh?
> The only difference a heavier rider could possibly make is to increase
> wind drag slightly.
The only "drag" force affected by the rider's mass will be the rolling
resistance of the tyres, and it will be relatively small. The amount of
"wind drag" will vary depending on how much surface area you're presenting
to the wind[1].
I'll leave the discussions of inertia[2] up to someone more qualified than
myself, like IK.
BTH
[1] You can test this by checking your top speed while lying prone on the
tank Vs your top speed while sitting upright. I suspect this might be why
fairings were invented... ;-)
[2] WHich is where rider mass really starts to have an impact.
Errm what's the difference between being fat and being heavy ? I would have
thought fat was a subset of heavy (as you could also be heavy through being a
serious body builder or a deformed Tasmanian without too many limbs and heads)

This was the same bike which was pushing shit uphill achieving a max speed of
80kph in 3rd gear into a headwind on the highway on the way to Mildura last
year with about 100kg of rider and luggage on board right?
Nev..
'03 ZX12R
'02 CBR1100XX
The Cycle magazine CB250 road test tached the CB at 6555rpm going 60mph.
I've wired up a digital TinyTach to my CB and at 65mph it's spinning about
6900, at 70 the numbers were dancing around 7300. Max horsepower is reached
at 8000 revs (max torque at 6500) and the redline starts about 8500 rpm.
Compared to scooters like the 14K rpm EX250, the CB is not spinning all that
fast.
The bike will easily tolerate a drop of one or two teeth at the rear
sprocket giving it longer legs for the highway.

As with any naked bike. Fit a screen and tank bag.
> This sounds very interesting, where does one obtain these jets from?
Part numbers from the US CB250 parts catalog:
#38 -- 99103-KR3-0380
#115 -- 99101-GHB-1150
It's been my experience that these jets combined tend to be too rich. The
CB suffers from lean low rpm carburetion, but the top end is adequate. You
could run just the #38 pilot jet to hasten warm-up, eliminate off-idle
stumbles and improve low rev torque, and then shim the needle to dial-in
high revs for that nice tan spark plug. OR, simply reset the pilot screw
(airscrew) and shim the needle. At the Yahoo group the shim mod is
described and illustrated in the Files using a single .024" washer. You can
pull the top off the carb for the mod without having to remove the entire
carburetor like you would for the jet swap.

Also rolling friction, mainly due to tyre displacement.
You can, to an extend, negate this with a bit of extra air
in the tyres. It's amazing the difference this makes to
a low-HP bike ...
... and yes, JL, getting up hills takes a bit of a run-up :-)
Yebbut, unless the blood of Honda has lessened, even a fuckerty
CB250 isn't redlined at 100 in top. Sure, sure 6-7k out of a
9-10k redline, which doesn't say "casual" to me either.
And Freeways don't tend to go up hill[1] and down dale[2],
so odds are Morphet is not going to have to change down
to fourth for his 24 minute commute, and can thus avoid the
merry song of the bouncing valve no matter his weight.
Anyway, I'm yet to be convinced that soundly flogging
(uh, below the redline) a (modern, japanese) bike is actually
bad for it, so long as it gets properly maintained.

Yup another 20 kilos and an absence of a screen up hill in a headwind
will do that. :P

I would actually go so far as to state that a good long (fast) ride
makes the Spada run _way_ better - I'm pretty sure it actually does it
good, not bad...
(Of course, 24 minutes on a freeway doesn't count as a "good long fast

I'll agree with big here.
I've had a couple of CB250's in the garage. Orphans and strays...honest!
After most of their lives as learner mounts, a good few rides at, or
near red-line, does seem to make them feel much better. ;-)
