Best pre 78 125

[holeshot buddy]

the top came off the bing and it holed the piston :'( doh

mine is set up nice ported modified piston 32mm bing
crank done runs 15to 1 comp
it will go on the back wheel in most gears with a 6foot 90kg rider
also very very light just got some remote ohlins for rear to put on
will have it at cd8
most didnt like the vb125 the rear end was not as good as the va
suzuki rm125 A B were best jap pre78

their wouldn~T be much difference between a RM A,B

Longer rear shocks with resivouirs , longer & way better forks , Motor has different bore and stroke, different exhaust, conical front hub, different swinging arm ,So yes their very simillar

thought heaps of difference between A and B model
