will these fit??

[ratta tatt tatt]

hopefully these will fit my bike. I don't have all the knowledge on switching out parts so that's why I am asking!!

the rims on my 1977 CB550K have gone to crap and I have found a set from a 1981 CB900. Before I buy them I thought I would do some checking around and here is the best place to do so!

so my wheels/rims are:
>front wheel is 100/90/19 with a single 280mm disc brake
>rear wheel is 120/90/18 with a drum brake

the wheels/rims on the CB900 are:
> front wheel is 110/90/19 with dual 280mm disc brakes
> rear wheel is 130/90/16 with a single left side 297mm disc brake

I want to think that they may not fit my bike but I thought I would put the question out there and hopefully someone will be able to help

cheers

Theres a big clue in there regarding the back wheel, you have a drum brake and the one you want to replace it with has a disc, so unless you are a pretty good fabricator and machinist I would say no.

I would imagine yours are spoked wheels and the replacement being from a CB900 are comstars, do you want comstars?

The front being a twin disc should not matter too much. If the axle diamteters are the same it could be made to fit.

Its rare that wheels will be a straight swap even between the same manufacturer without a least having to have spacers made.
With time, money and skill virtually anything can be made to fit.

ok that's what I figured. I don't want to have to do major fabs to get them to work on my bike. I don't mind the comstars look though!! I know I can get new rims from Dime City so I should just replace that way

thanks for the info

I know that was the tire sizes .....but if you look closely that last number in the tire size is the rim size !!!

This is true....but that 19" wheel could be 2.5 inches wide Vs a 1.65 inch stock frt wheel...the wheel width is what you need to have a measurement for...the hubs may be very different too....just because the overall diameter of the wheel is the same does not mean it will bolt right up....
