1982 Honda CB 900 with 10 Speed Transmisson??
« on: August 13, 2011, 04:45:59 PM »
I found a 82 Honda CB 900 10 spd for sale from a friend for $1,000. New rubber, runs great, rides good, needs new fork seals, he has them.    I rode it, but that 10 speed is weird as hell. Never even heard of it before. Anyone here familier with them?  Seriously thinking of picking it up just for the freak factor.

What gives it the additional 5 gears?  A two speed rear end, or some sort of overdrive built into the transmission?  Sounds interesting .... LO range for the twisties, and HI for the highway.

It has a second shift lever above and behind the usual lever. You can split the gears like a semi or just select high in fifth and really drop the RPMs.  Was cool to play with to say the least. I'm tempted to buy it, but have never heard of one.

that bike uses an engine designed for a left side drive but has a right side shaft, so there is basicly a 2 speed jackshaft to move the drive from left to right. heres an excerpt form an article on it.
The Sub-transmission is used as a "jack shaft". That is, in order for Honda to use the CB900F engine in conjunction with the GL swingarm and final shaft drive, power must be taken from the CB900F's left hand power take off and transferred to the GL's right hand side final drive shaft. The "Jack Shaft" was given 2 gear ranges ranges at relatively low cost. Most CB900C riders use the 2-Speed Transmission more like 6th gear overdrive. Leaving the bike in low range while shifting through the normal 5 gears, then shifting into high range once up to speed on highway, reducing engine rpm significantly at touring speeds.

Had something similar on an old Trail 90 though that was a 4-speed. That bike had an ultra-low range that would barely top 25mph in 4th.

Hi Low range transmission, they are pretty cool and a good bike. I ride with a Honda guy who had 256000 miles on his and its a screamer. That double shift lever makes you scratch your head when you first see it!

Reminds me of how we drove a buddy's Austin Healey 3000, with Laycock de Normanville overdrive (I think that's what the dash label said).  Here was our shift pattern when we were trying to impress ourselves!:

1st (no overdrive in first)
2nd
2nd overdrive
3rd
3rd overdrive
4th
4th overdrive

Kind of cool ..... a seven speed transmission, sort of.

An old buddy I shared an apartment with had an AH 100/6 with that tranny.  8)  His 1st gear had to be replaced about every 20K miles.   :'(

I had a Volvo P1800 w/4spd+ elect. overdrive on 4th. It was like having a 5th gear.   8)

My son had a `69 Kawi. 110cc semi-dirt bike w/a dual 4 spd tranny.  8) Like said the low range was so low you only used it in the dirt.

I had a 1980 model in the fast blue color.

One of the best bikes I ever owned. Bought it used with 23k on her, sold with 87k. Got a phone call from the new owner a year and a half later said just passed 102k and couldn't kill it. Quite reliable.

The tranny had a splitter in it as previously stated. I kept mine in the low range around town and switched to hi range fifth on the freeway...an overdrive of sorts.

Even though I am passionate about Guzzi's now, if I could pick one back to have back from my Honda years it would be that one.

The last year of the run Honda bored it out to 1000cc. Didn't need to. The 900 had plenty of gofast in my opinion.

The CB900C was a great bike,. only 'weak' point I can think of is the Air cutoff valves. Just plan on replacing them every 20 years or so. The air cutoff valves do NOT like ethanol and you have to split the carb rack to replace them. I have a CB900C in the garage right now even. SWEET tug for a sidecar.

I remember that bike and it got good reviews.  I never heard anyone brag about the two-range transmission, though.  I think it was an answer to a question that nobody was asking.  As I recall, this model Honda also had the modular wheels.  They were cast but you could replace and rebuild the various cast sections of the wheel - another answer to a question nobody was asking.

My brother has 2 and is in the process of rebuilding one. He has been riding it for 20 plus years and loves it.

An old friend here in town years ago used to let me come over and tinker with an old bike he had. The deal was if I could make the miserable thing run I could ride it. Was a 1974 Suzuki TC125. Had a 4 speed tranny with a flapper on top of the left case you could kick with your heel and switch between low and high. Low was really LOW.

Thanks for the memories!

There's another one prolly still in the boneyard at TMS in Watertown if you need parts.  My BIL traded one in when he got his Cali.  The two tone blue if it matters.  It was a great bike for many years.. 100MPH was at the bottom of the power band in fourth high.

they're fixing that one up Atavar. Very very slowly.
I think the body work is off getting fresh paint right now.

My brother-in-law had a nice one with 82k miles on it. Ran fine, had a small leak from the cam cover was all, cosmetically very good. Until he let it sit outside uncovered that is. He "needed" a new bike (big Suzuki cruiser).  ::) Last I heard the "kids" that bought the Honda had it whipped back into shape and were riding the heck out of it.

I thought the concept of a dual-range transmission would be best applied to a dual-sport/adventure bike - low range for off-pavement, high range for the road. I'm surprised none of the manufacturers has done anything like that. I guess everyone is too conservative and afraid to do something a little different nowadays...

always heard good things about them - nice option on the highgway for low rpm's - engine is probably bullet proof

I had a friend who owned an '82 CB900C back in the late '90s.  It was smooth, comfy, and reliable, but not my favorite dual range motorcycle.  That would be the '70 Suzuki TC-90 Blazer.  It had all the utility of the Honda Trail 90 with a stronger 2-stroke engine and styling that said "Bengt Aberg" rather than "John Deere".  I never owned one, but lusted after them badly as a young fellow riding a Honda '68 CL-70.  Oddly, I ended up buying my son a '70 Trail 90 for transportation in high school.  It was cool in an agricultural sort of way (Caterpillar Yellow was the perfect shade for touch-ups).

Low range for town.  High range for the interstates.  Had a friend in Mesa that rode his all over.  Good bike.  Manual shift Convert.

Ha!  That might have been me way back when riding around following Gene..  never could get in front of Gene, didn't matter what he was riding.  He was the most unconsciously savant riders I ever knew.  On the Sporty or the G5 there was nobody could out-ride him and no obstacle he couldn't get past.  I guess trials riding does that for a guy.

 I have seen a couple that were used for sidecars,  Actually wanted one myself.
The only down side is when they get old remember they are 4 cyl inline.  That means carb rebuild X 4
Electrics X4 etc.

I bought a 1980 CB650 new.  I think I sold it in 1984 or so.  My recollection is that it was a great bike.  Don't know if I would trade it for a 900 or not...

But my memory may be clouded by nostalgia.

I had the 1983 CB 1000 Custom .... I only had it for one season back in '89 or there abouts... The dual range transmission was not a big issue or oddity at all. Just keep it in high range for around town and if you go out on the interstate give that second lever a kick and you're in sixth gear... I had no trouble with the bike and did do one cross country trip with it. The '83 had several styling updates over the '82 and earlier 900 customs including standard cast wheels and updated gauges. It was a nice bike.

In 1989/90 I built a dump truck and chose 5X4 trans set up and it was a blast in the shorts to "play" with such as "twin stickin' " and shiftin' in reverse 3 times ;D
