6 speed bandit 1200

[tm300enduro]

Hello, I have a 2000 bandit 1200 and am wondering which tranny gears do I need to make it a 6 speed, and or all parts needed to get this done thanks

A whole 750 gearbox - not just a case of swopping odd gears. The cases are different across the gears so some fettling may be required. But question is WHY? Smaller / thinner gears, more of them in a motor with more torque that doesn't need them?

[Swirl]

Thinner gears + more torque = cooked box, although it can be done and has been done, as above why

Welcome to OSS 

As x2 above, can be done need full gsxr750 box, bearings are not the same so you need to do some work with that.

Better and easyer ways to get more performance out of your bandit.

You could try fitting a dual rear sprocket and a shimano derailler...... no gearbox mods needed .

How to is in Frankenstein's guide ..blandit motor is almost the same as the 1127

 750R 6 box in a 1127 motor
The only hard thing here is to have a hole drilled through the gear box shaft, for the pushrod.
The 750 6 boxes have a single row bearing on the output shaft, and the clutch does
not have a diaphragm spring. So the easiest 1127 engines to put a 6 box in are the ones with a
single row bearing on the output shaft, and no diaphragm clutch, ie. only the GSXF1127 engines.
In these engines the 6 box drops straight in, only the shaft has to be drilled.
Second easy would be an 1127R engine with a diaphragm clutch, but no double row bearing (88-90).
In this case the box would still drop in, but for the clutch one would have to use the inner
clutch parts from a GSXF1127 (with normal springs) and the outer clutch basket from the 1127R
(with a straight cut gear, not helical).
Most work is in a 91/92 1127R where one would have to match the clutch as above + find a
solution for the double row bearing (the solution is actually to turn the double row bearing
inside out, and make a little hole for the small pin).
Of course the shift drum and forks from the 6 box have to be used as well, but they drop in
any 1127 without problems.

 

Simples.............

Thanks for the responses, I did read the Frankenstein post about this, but it didn't say what gearbox to use, like any year oil cooled 750 or?

Also its more for being able to keep its normal acceleration but also have easier cruise on the freeway.

Maybe at some point ill do the whole big boar kit but it already has 1100 cams, jet kit, ignition advance and holeshot header, its fast for now lol

Bahhhh....put a turbo on it....leave the gearbox alone....lower the rear sprocket by 3 or more teeth.....you will have all the cruise speed you want.....and special whooosh whoooosh noises too !

You could put a DOT head on it.

Ps, is that the 400 bandit rear end on it (seat unit)?

[tm300enduro]

I think I’d do the big bore to then keep the stock head but again the 6peed isn’t so much for high performance and yes it’s a 400 tail section

Looks good
