Is it possible to bolt a CR500 jug onto an RM125 bottom end?

Is it possible to bolt a CR500 jug onto a RM125 bottom end? Or would I have to buy a CR500 bottom end too?

[TheArmageddon Lemon]

...no

Honda power.

Totally dude.

 

Suzuki actually designed the RM125 clutch with the Honda CR500 top end in mind.

Should bolt up, gives you alot more compression if you use the rm 144 piston aswell. Don't forget to adjust your muffler bearings and change ( or clean) your powerbands.

Not on a 125 but the 125 barrel will bolt straight onto a CR 500 bottom end, i did it years ago on a 2001 CR 500 the thing ripped 5th gear on the back wheel everywhere.

Yes. The cylinders from a Chevrolet 350 V8 also bolt on.

Using the CR500 cylinder is just a compromise.

 

Better to go with a stroker option for more torques. I carefully measured up the RM125 casings and found that by using 20,608 crankcase gaskets I was able to widen the casings enough to install a larger 15m long crank to increase engine output.

Admittedly I did need to source an extra few cylinders to make it run properly but the increase in combustion events per revolution really helped smooth out the power delivery. I was able to drop one tooth on the rear sprocket which was a surprising bonus as the bike now weighs 7 tonnes...

 

Here's the vid of them making my new crank. Engineering buffs should dig the machining process.

All you need is a TIG welder, hammer and a file! Also take measurements with a micrometer, mark it with chalk or a crayon and make your cuts with a chain saw!
