Bucket wheels

[r1johnkt]

Hi I'm new to buckets, just bought my first! Its a stunning cb125 but it has 18" wheels. I would like to change to 17' so I can run slicks as this seems the thing to do. My question is what sort of wheels can I buy to fit the cb and whats involved? Thanks John Does any one have a set of wheels?

vt250 has 17" drum braked rear wheel 2.5" wide
vtr250 same but 3.o" wide
fxr150 front wheel , fzr250 front, gsxr250 front, nsr250 mc16 0r 18, plenty to choose

The correct rim size's for RS125 Slicks 90/90 front and 115/70 or 120/60 rear are 2.5 X 17 front and 3.5 X 17 rear. We use 18psi cold front and rear in the ESE bikes.

Older parrallel twin TZR250 wheels 2.15 X 17 front and 2.5 X 17 rear and running a disk brake front and back. Although not strictly the correct width are common on the CB125's at Mt Wellington.

I suspect TZR wheels on CB's at Mt Welly are so common because most of the CB's there were converted sometime ago and the parrallel twin TZR rims were plentifull then. I think the later reverse cylinder TZR rims are the correct width but hard to find.

Yow Ling lists other good options.

[Yow Ling]

You can always do what I did and use a 3" x 17" FZR (400?) front rim on the rear.
Sure you don't have a cush-drive (rubber blocks) but not that important on a bucket and I found that DT175 sprockets fit perfectly onto the disc bolt pattern.
Only issue I found was it was a tight squeeze onto the swingarm of the RGV150 frame but that's the frame's fault !!!

(I use a 3MA TZR front rim on the front).

Be aware that rear wheels are not too complicated to change. fronts take a little more work to fit, they can be fitted to the original forks, and the original forks are great if set up properly. Often forks are also changed to improve the front end and make wheel changes easier .

I have a mono shock CB and run a VT250 wheel at the back and NSR250 wheel at the front. Both needed spacers made (really need access to a lathe) but apart from that it was relatively straight forward to fit!

My 74 TZ did not have a cush drive on the rear wheel, the sprocket bolted directly to the rear hub. All the early Yamaha Production Racers with wire wheels were like that, didn't seem to be a problem.

some fzr250's had 2.5" f and 3.5" r rims

These would be my pick if I could get them.

[speedpro]

some fzr250's had 2.5" f and 3.5" r rims

2.75" and 3.5" - 3LN model
2.15" and 2.5" - 2KR model

actually

[Pumba]

2.15" and 2.75" - 1KT Model (I think)

I have always thought that a 3.50" rear was a bit big? Especially for the cart track (NOTE not bassed on any hard facts)
