Wondering what the stock offset if on an NC30 wheel??

Also, any idea what the widest wheel is that can fit in an NC30 swingarm? Im guessing a 6.5" wheel with a 200mm is to wide and would rub?

surely you mean 5.5 inch ? not even the RC45 wheel is 6.5 and wears a 180 / 190
if you do mean 6.5 then yes, way way too big

Triumph Rocket has a 200 wheel, try that.

But to be serious for a moment, a bike turns by laying over and how fast it can lay over is governed by the distance of the tyre from one side to the other, so if you stick a great big tyre on it you'll have a slow bike. Second thing is big tyres weigh more, so you use up more of the engine turning the back wheel + tyre, you can't accelerate as quickly and it takes more brakes to slow down.

For the bike the 150 standard width is about right, it's like honda actually sat down and thought about what was best for the bike. What they didn't know was that most tyres are now made in 17" wheel diameter and that a 160 has a much bigger range of choice.
So .... what you want is a "new" wheel, 17" diameter that takes a 160 profile tyre, or a RVF 400 wheel.

Thanks for the reply... I asked cause i am trying to work on a custom application using a nc30 swingarm.
the wheel i was thinking of was a car wheel.... its a 17x6.5 which was the narrowest wheel i can find and pretty much matches the front wheel im using. I can have it narrowed to 5.5 which is what i will probably do to run a 180... if a 180 would even fit centered on this swingarm.

Anyone run a VRF750 wheel on an nc30 swingarm?

thanks

yes thats a common mod. do a search, rick oliver does the conversion kits

is there a website for Rick Oliver?

I did a search on google and all i came across was a pdf list of parts. I was wondering if there where any pics anywhere of the vfr conversion.
