Light weight wheels

[Vishnu]

So my project is.......doing....
Sittin in a garage ssslllloooooooowwwwly coming together.

I was wasting time on ebay looking at gsxr front forks (2008-2010) and I noticed that they have a 6 bolt pattern on their front rotors.


I called Carrozzeria and asked about the bolt pattern. 120mm. hmmm same bolt pattern as the drive hub flange for all the Suzi shaft bikes..... using one of their light weight wheels would shave about 15# over stock. Sans bearings their wheels weigh 7# thats just the rear rim, with a gsxr front end it could be upto 30# of weight saved...

I am wondering if it would be possible to;
a) bolt the flange directly to the wheel (remove pins as they are threaded in)
b)widen the swing arm to accommodate the wheel. I think this would be required. IF bolting onto to outside of the rim, the spline to rim ratio is now moot, as the splines would be sitting on the outside of the rim width vs the inside of the rim width.
c) adding a second u joint to the drive shaft to deal with new angle of the drive shaft.
d) mono shock conversion

Thoughts?

You forgot the bearing and mount for the angled shaft drive and you'd have to lengthen the drive shaft

Seems like you'd have to add on as much weight modding the swingarm and drive shaft as you'd lose in the wheel.

Better to just get a chain drive bike

Sorry, my thoughts were that you are assuming that we all know "your project" intimately.

If you hadn't mentioned the shaft drive, most of us wouldn't have the slightest clue what bike you are talking about.

Actually, we still don't, other than the fact that it's a shafty.

I'm not much on engineer, these are just thoughts...

So Big T, what kind of bearing and mount would be required?

In which case my thought would be that you should forget it before you kill yourself...
