Titanium parts...
Denis Concordel
my attention got caught by a display case full of Titanium hardware.
I stopped by and asked for a price list. Here are a few items (as a follow
up on some previous posting regarding shedding weight of an XR).
Titanium front spoke kit $199.95 (call it $200 )
Includes spokes (Titanium)
and aluminium nipples
Handlebars $179.95
Includes cross bar and pad
Swing arm and pivot bolt $395
Sproket bolt kit $15
Front end bolt kit $95 to $150 (depending on the bike)
Hex head bolts 6x12 $4.66
6x60 $8.00
8x35 $8.20
8x50 $9.20
Hex head nuts 6mm $2.66
8mm $4.66
10mm $6.66
Looks like for a 2 wheel spoke kit + handlebars + swingarm kit + wheel
axles+ a bunch of various nuts and bolts, one can spend in the $2000+
on that type of hardware.
It'ld probably be cheaper to sell the XR and buy a Husaberg.
BTW: there was a Husaberg 600 with Electric starter in the Husaberg
booth with a big sign saying '95 model.... Since it already has the
battery, making it street legal will be child's play (just add turn signals,
mirros, horn, brake ligh and you're done). The conversion looked real neat too, with the starter mounted in front of the engine (between the engine and the
frame) and the battery hidden under the seat (where the airbox is on other bikes).

PS: I wasn't able to get the results for the last days of the ISDE, but
I think that the Italians got the trophy and that Stephane Peterhansel got
the overall.

Looking at those prices I know where I'll be loosing
my next 10 lbs from.
So how much weight loss would that kind of money buy you?
5 lbs ?

$395.00 is for making up a custom axle set (front and rear) and
swingarm pivot bolt. The owner of lightweight products told me
this would save about two pounds.

I have been calling around to places, the price list that you have
is from lightweight products. And have learned a few things along
the way...
1. Titanium must be welded in a pure argon atmosphere, if there is
oxygen contamination the weld will be very brittle and appear
purple in color.
2. One place said they had their metal certified to be .17 % oxygen
content and that I should ask what the o-2 content is on the metal
before you consider it.
3. Titanium is 52% the weight of steel with approximately the same
strength. I don't think titanium handlebars will save that
much weight over a set of pro-tapers...
4. A good rule of thumb is that it will cost you $200.00 per pound
to lose weight off the bike. e.g. to save 5 pounds, it will cost
you $1000.00.

Yeah, but I like a bike with an oil pump. Doesn't a Husaberg
have a "dip and wish (for the best)" oiling system. Isn't there
a reed valve that kinda pushes oil in the general direction of
the valve train? So how much metal came out the first time
ya changed the oil???
Just givin' ya a hard time dennis :-)

Interestingly enough, I was checking the tire test in the last Dirt
Rider, and I realized that there was a rather large difference in
weight between the various tires tested. As much as 3 pounds... Talk
about a place to start.
On the same subject, Dirt Bike recently did a chain test (non O-ring,
but the same should apply to O-ring ones) and from what I remember
there is a few ounces per foot difference between various brands of
chains.

Yeah, I think that's why alot of the motocrossers come with
Dunlop 737's. They have alot of space between the knobs so they
are pretty light. The 752 is a pretty light tire as well, I figure
it weighs a couple of pounds less than the IRC VE-33 that comes stock
on the bike.

I bought a postage scale that goes between 0 and 5 pounds in 1/2 oz
increments for 13 dollars at office depot day before yesterday.
Took it home and weighed a bunch of parts on the XR.
1. By going to a white brothers mega-alloy pipe, I knocked four and
a half pounds off the bike.
2. Switching from the stock chrome-moly bars to Answer Alumilites
knocks off a half a pound.
3. I am not sure, but I think switching from the stock 6 ply IRC
VE tires to Dunlop 752's knocks off another four pounds. I
did weigh the stock VE-35 and the 752F and the difference
is around two pounds.
4. I am not sure if the White Power Suspension is heavier or lighter
than the stock suspension. I'll add a pound for the hell of it.
So right now, assuming a weight with no fuel figure of 247 lb stock.
My bike currently weighs 239 lbs.
---------------------------------
Other potential savings include
1. Titanium Axles - 2 pounds. Price : $385 (ouch!)
2. Miscellaneous nuts and bolts - 3 pounds. Price : $600.00 (ouch again!)
3. Titanium Sub-frame - 3 pounds Price : ??? Guess $500.00 (ow that hurts!)
4. XR600 aluminum kickstarter - 3/4 pound Price ??? Guess $90.00
(I am not sure this fits yet, stocker is steel).
5. Machine 6061 piece for right footpeg mount 3/4 pound Price ???
6. Titanium spokes - 1 pound Price : $400 (oh no, it's hurtin' again!)
That would put the weight with no fuel at 228 pounds...
--------------------------------------
and it would only cost a mere $2000.00
oops forgot to add bars,pipe and tires $2350.00
Oops, forgot to add for psycho-therapy...
(I'd have to be crazy to go for this!!!).
Price 1995 XR list $3800 so $3400 with a little haggling.
Total cost : $5850.00 (plus white powers; plus psycho-therapy)

Okay, Okay, where is the line to get in for the Husabergs...

buy some bolts for my XR from Honda, cost $2.50 for each bolt, and $150 for each nut!
What a ripoff! This was from the cheaper Honda of TRoy too! That would add
up to $18 bucks for a set what a ripoff.

Yeah, but you don't have to get the solid gold with the diamond inserts
ones ;-)

I just remembered a tube shootout where they tested and weighed
various tubes. The trelleborg tube was very light and strong.
The Metzler Tube won the shootout. I'll have to dig it out,
I think the Trelleborg weighed over a half a pound less than
the Metzler.
I question the way they ran the test though. They pushed down
on the tube with a nail on top of postage scale and noted what
pressure would cause it to break. I felt that this measured
how well the tube resisted punctures very well. I felt that
it might not be representative of how the tube would respond
to a "pinch flat". Which I guess you could classify as more
of a tear.
I usually run Metzlers. I have run Michelin Air-stops and
they seem very good quality as well. I would like to try
out the trelleborg tubes. Anybody out there given them
a try?

What I want to know is has anybody tried out these new foam
innertubes that are used in place of a regular innertube, and
supposedly guaranteed forever? What dya say? How hard on
the wallet, how easy to install?

Owning both a Kawasaki and a Honda I can tell you that the quality
of the hardware on the honda is quite superior. Looks like you
have to pay for it though...

at the ISDE. The bib moose (150 bucks), and tech tubes were being replaced
after the first loop. They apparently would overheat and actually explode?
These things were shreaded!
I have had a lot of luck with heavy duty tubes and running anti flat (thorn
proff) goop in the tubes. Matter of fact, I recently bent the front rim
on my XR on some rocks but did not pinch my tubes! I'm certain that the goop stuff
helped keep the tube from pinching.
The inserts would be good in areas with a lot of thorns but not so many
rocks. But for the price they seem hard to justify unless your rich or
you race and don't want to chance a thorn flat.
BTW just don't run over any thorns or rocks and you'll be fine!
Latter,
