Thanks' Neo.. I'll consider your Info' actually those things that you mention is the next thing that I'm going to think of' after I finished this wheel issue.
Do we have some good suppliers of after market parts here? aside of Rick O'. I'm just working here in Thailand, sometimes is hard to communicate to Thai' people. specially on bike parts. Better to order import parts if i do know what I'm going to buy. right..!
What about up side down forks for nc 35 , what is the standard measurement of it? Does it has pressure and strength or something?

A wider tire will increase grip, but will require more effort to turn the bike. As far as I am concerned it is detrimental to performance.

But it is not my bike, it is yours, so best of luck fella.

Thanks fellahs' ...I think I need to change my decision on wheel. I also emailed Rick O' for the conversion kit, I think I need to look for the wheels of VFR750FR-FV (5-spoke, 5.0 x 17", 4 bolt fitting) before I get one kit. Here in Thailand its hard get this kind of wheel.s As rick O' explained to me, I learned that that 5.0 x 17" wheels is not much difference from the stock wheels. But I hope I'll get one.

And Neo' I like the one you said about good rear shock and ohlins front forks with large brembo radial brakes and master cylinder. is there any specific ohlins front forks for rvf. Co'z right now there's somebody selling a slightly use Yamaha r6 ohlins front forks here in Bangkok.You think that would fit? and with our stock upside down forks' is there any brembo caliper that would fit?
For rear shock we have it here' YSS are making these kind of shock for rvf400.But costly man around 6-700$.

Really need help thanks!

Lots of info here.

I have the VFR750 wheel fitted to my NC30, it is mostly for looks, and haven't found ay problems with trying to turn the bike (it may only be more difficult at high speed/racing, but I only do the odd track day now and again!)

Hope this helps. If you want any more info, just ask!

As for the front forks, - to fit the R6 ones, you will probably need to modify the yokes, and get new clip-on handlebars too, this will probably change steering locks too.

Lots of things to consider.
