best rim size

[lrcarl]

hi all,doing a ypvs/mito have two sets of wheels 4"back,3"front to run 140/150back 110front tyres
also have 4.5"back,3.5front to run 150/160 back,120front

  wider rims look better but will they make steering slower?

 thanks carl

Fat tyres will 'look' better certainly, Mo' Manly.
But quick responses/agility of the bike will reduce proportionally to tire section increase.
Pick a compromise? Likely by experiment.

that my thinking,going to try both setups also have read tyres for wider rims
were designed for 600's so do not work as good on a lighter bike

They will work if they are softer and heat up quicker

the lighter the bike the longer they take to heat up

the rim size will also determine how quick the bike will steer for instance the same section tyre on an 18" rim will steer quicker than on a 17" rim

your steering is also affected by the rake of your forks too, think chopper Harleys with a big rake forward, they steer slow, or a Buell with no rake and it steers real quick

Lrcarl, I'm having a similar dilemma.

At present I have a set of 3XV wheels on my hybrid build. The rear is a 160 at present.

While it certainly looks good I too am thinking its a bit wide. I was going to use a 150. However the sprocket carrier needs a fair bit of work, so I might go for an FZR400RR wheel instead with a 140.

Hblair is right with the tyre warming thing. I asked my local (bike friendly) tyre fitter about Pirelli Diablos on an RD hybrid and he was concerned they would not get up to temperature with the lighter bike.

hi jon,if fzr is 4"could still run 150 tyre.i have gsxr400gk76 wheels(wide set)using gsxr forks so have rgv front wheel(straight swoop) mito back.

I dropped from a 150 to a 140 on my hybrid and noticed it dropped into corners better

thanks steve,how does a rgv wheeled/hybred compare with stock wheels?

To be honest at first I was a bit disappointed.

First built it with a standard rgv front end (3 inch rim 110 tyte) and rear fitted (4.5 rim, 150 tyre) with modded dog and legs and h link using a ypvs hagen shock.

Brakes were a lot better (had used gk76 discs and Nissin 4 pots)

The wider rubber and smaller wheels gave a lot more grip and no longer had the small bike spindly feel but suspension still felt soft.

I changed the rear to a proper nk racing kit and used an RGV showa remote res shock and had the forks revalved, resprung and damping adjusters fitted by Maxton which made a massive difference.

It now feels like a modern bike. Taut with no wallowing.

Also changed the brakes to tokico 6 pots, fazer master cylinder and galfer discs. They are now as good as any modern sports bike. This is a bit ott and mainly done as my discs were ridged and the calipers were a bit sticky so needed work anyway.

Forks would probably have been a lot better with new springs and heavier oil.

Only handling issue then was it didn't like it if you needed to turn in more while on the power. You had to back off the throttle.

Wanted a change of wheel colour so fitted 400 bandit wheels as I got them cheap which had a 4 inch rear and I got a deal on a 140 tyre

Now no longer has the turn in problem.

Have Diablos fitted to my 600RR.. Marvelous tires ! Certainly so compared to the oem Bridgestones.
These don't actually need to be heated up to work better than Bridgies did when they were well heated.
RR weighs a 'claimed' 157 Kgs :-) Regardless, Not massively heavier than my 350

thanks bare,good info
