hi in helping a friend with a 1976 cb150 bucket. Its all new to me as I used to race a 600 in the australian national series. These little buckets are great fun.Anyway I was wondering does anyone know if its possible to fit a 6 speed box if so what model bike do I get one from. We are in Tasmania Australia. Looks like bucket racing is bigger in NZ. cheers to you all:third:

That must be a super 'NO' to that one.

1976 is just a bit too far back.

A 150cc motor would struggle driving it.

Would love to be proved wrong on this one :)

BTW: Welcome to KB.

Your regulations will probably restrict what parts you can change (the auss rules are fairly strict I understand). However it is mute point I think all those Honda singles (CB125, XL125 etc were 5 speed).

I think one model of the XL125 (S) is a 6-speeder, but for those type of engines (like the Loncin I run), a 6-speeder isn't really required as they're a mid-range power delivery type engine.

XL125S and XR200 had 6 speeds but wether they fit into a '76 engine could be an issue.

If you can't squeeze the xl box into the CB see if you can graft the top end of the cb onto some xl cases. I have a cb125 with xl box but I bought it as it is and really have no idea whats in the engine truth be known.
