after market 40 spoke rims

whats up guys- i have acquired quite the pile of parts for my gsxr front end conversion- i just ordered a front hub to make things a bit easier on me from the guys at cognitomoto.com.

im looking to lace up lighter new rim- im either going to keep the stock wheel size with the 19 up front and 16 rear(in order to get the best geometry i can with the frame im running) - or bring the front down to a 18 ( ill worry about the rear once i figure out if im doing a new swing)

anyone have any good experence companies that make a 19x3.5 alloy rims?
and when a rim is 19x1.85 its not really only 1.85 wide is it ? im confused on that measurement.

cheers ya'll!

the measurement is between the bead surfaces. 3.5" seems really wide for a 19" front rim. it will add alot of rotational mass with a big tire to match. Buchanan's does carry a 19x 3.5 though

I highly recommend Buchanan's. I have custom drilled Excel hoops for my custom built wheels. I used modified 40
spoke Harley Davidson wheels. They also made my custom HD spokes as well. I went with modern sizes of 17" X 3.5" and a 17" X 5.5" for the rear. Running a 120/70 front and a 180/55 rear tires.

Greetings,

I too am going with the front end GSXR conversion from CognitoMoto. They offer the completely assembled hub/spoke/rim package for this conversion, guaranteed to be compatible. There stuff is definitely pricey, but I'd say its all quality. I'm going 18x2.75 to replace the stock 19" front. That's the same size rim they used on their Fox CB350 build.

I also had CognitoMoto do a new custom Sun rear rim on my stock drum brake hub (with their hub service and anodizing, installed new AB bearing & seal kit while their at it). Its a matching 18x2.75 rim; both front and rear tire diameter is 4.00x18. Remember to confirm that any new tire diameter on the rear will clear your swing arm and tail/fender/license plate or whatever you have back there. But if you're going to a new swing arm then you have lots of options. There are charts out there for recommended tire size to rim size compatibility; check the Avon Tyre website, for example.

And when purchasing stuff from CognitoMoto be certain to select all options you want i.e. additional charge/item for rim color anodizing; speaking from experience on this one :blush:
