Just out of curiosity ...
What's the multi-cylinder production bike with the smallest cylinders? I got
to thinking the other day how my CB-1 has four 100cc cylinders, and I don't
know of any bikes with smaller displacements per cylinder. I suppose the
FZR400, CBR400RR have similar configurations, but does anything else have
anything smaller - scooters not included - ? Even the Ninja 250 has two 125cc
cylinders.
Just askin',

They have four-cylinder 250s in Japan -- they're not exported to many

The first one I can think of is the Honda CB3450 four.
Paul
> Not sure but the CBX had 6 cyls,what was the displacement?
A bit under 1050cc. 1047 or some such odd number.

I've heard that Yamaha made a 100cc TWIN in the late 60's or
early 70's. Two stroke, of course.

****How about the Honda 6 cyl 250cc road racer (60's vintage)
****How about the 1966 Honda CB160 (twin)
****How about the Honda 50 Cub...(street legal)
oh shit on this old crap. where's my Honda Blackbird???
Yes Yamaha offered a 100cc 2 stroke twin YL1 and Electric Start model
YL1E both with Pressed Steel Frame in 1966 and 67.
Then in 1970 and 71 they had a cute little 90cc with a tubular frame
dubbed the HS1 and HS1B. This was replaced by the LS2 100cc for 1972
with a tube frame. They also had the YAS1C in 1968 followed by the AS2C
IN 1969 and the RD125B in 1975 and the RD125C in 1976 these were all
125cc with Twin tube frame and were quite high performers for there
size. This goes back to when Bob Braverman used to write for Cycle World
if any of you still remember him

I recently sold a service manual that covered Honda 125-360 twins, made
from 1964-1976. That would put the cylinders of the 125 at 62.5cc each.
Ask jdb...@onramp.net, he bought the book.

Bryan,
One has to look back at Honda's Roadracer's of the 1960's. I forget the
model number (cb166??) but Honda had a 250 cc six cylinder (41.67
c.c.'s/per cylinder) , and a 50 c.c. twin and a five cylinder 125c.c.
bike (25 c.c.'s per). All world champions, I believe.
The RC165. They're small (I helped nobby Clark... in a useless,
"hold this" sort of way... rebuild one after it grendaded at
Daytona this year with Jim Redman riding). But Honda's 5-cylinder
125cc is even more minute. However neither are "production motorcycles".

Hmmm. That would make each cylinder displace about 862
cc's............

Well, the FZR250, ZZR250, and so on all have 250cc engines which have 4
cylinders.
I think I've got you beat here:
About the same ('73-ish) era, Yamaha made a 90cc twin - pretty nifty
little street bike - Sure would like to get my hands on one today..........
Signature line? WDNNS signature line!

and i believe Benelli (remember them!) made a 250cc 6 cyl also!

FZR redlines at 17500, CBR at 19000! No power but lots of noise!

Along with the Benelli Quatro (250/4) and the suzuki stinger (125/2)
Benelli made a six-cylinder 750 street bike in the early 70s. No
6-cyl 250 race bike that I know of. Kel Carruthers used to race a
a very cool looking, green/gold 4-cylinder Benelli 350 though.

Actually, they put out more power than Harley big twins. 45bhp measured at
the back wheel is the standard amount for a four cylinder four stroke 250.
I'm almost 100% sure Honda made a 250cc 6cyl race bike, but I can't find
the magazine article anywhere...
anyone?

I recal reading sometime around 1980 in a bike mag about a past racing
bike of quite small displacement having 8 cylinders and something like
16 or 18 gears. Mentionned something about a very narrow powerband....
I don't remember if the bike was from the 70's or 60's but the article
said racing rule changes were responsible for its demise.
anyone?
What is this... the third comment about the RC164/5 in this discussion?
Read the thread, folks. Yes, Honda made a 6-cylinder race bike in
the 60s. It was a factory GP bike raced by Mike Hailwood and Jim
Redman, among others. It raced and won at IOM as well. It's a
frightening racebike weighing under 300 pounds with a practical
redline over 20k. But with only six of them ever built it also
ain't a production motorcycle.
Let's not forget the Honda CB350Four (347cc) made from 1972-1974
(never officially imported to the UK). It's very similar to it's
replacement, the CB400F but funkier and rarer.
Cheers
Check the history books...I think they red lined at around 11,000
Greg
Honda 50cc 5= 25bhp/27500 rpm
Suzuki 50cc V3= 22 bhp at about 25000 rpm
Suzuki had a 500 rpm wide powerband, so it ran a 17speed box
Look it up... Cycle Mgazine, circa 1967.
Those would still be 40cc+ cylinders. Not nearly as small as the Honda
and Tohatsu 50cc twins (25cc cylinders).
George
But I would not be surprized if something smaller had been built, but was
not popular/successfu, and maybe not a motorcyle (ie moped, scooter, or ?)

Lord Julian Spagthorpe, inspired and perturbed by Mike the Bike's
resounding success in the '66 season, charged the Spagthorpe Ferret Works
in Ipswitch on the Halfshell with making a World Beater for the '68 season.
This bike was indeed smaller, less popular, and certainly not as
successful as the Honda. The project name was Feral Flea. It was a 125cc
(124.5cc), eight cylinder (15.563cc each), 40 valve, QOHC, 55BHP @
38,000rpm, 212 lb dry, 154mph, marvel. With a bore of 1.57 cm and a
stroke of 1.24 cm, this dual-square-four (quad cranked) engine was a
technological marvel. Unfortunately, immediated after the conclusion of
the first test run, the entire outfit, including the test rider, Caso Di
Gorgonzola, was eaten by a pack of dogs drawn by the ultra-sonic whistling
of the exhaust note. The only known photograph reveals only the
handlebars protruding above the rabid, frenzied, pack. All that
remained were the soles of Sr. Gorgonzola's boots, which were delivered to
his grieving widow personally by Lord Julian. (She later went on to become
the second Lady Spagthorpe... but that's a subject for another newsgroup.)
