RVF Tyre & chain hitting?

[Drunkn Munky]

160 rear and 525 chain will cause it to hit each other... tried and tested

Even with the rick Oliver kit?

I hope not or I'm stuffed

Surely its easier and makes more sense to just go for the 520 chain?

I have just fitted the kit. It works really well £16 well spent.

Not when you have a brand new 525 renthal sprockets and chain.

it's got nothing to do with the pitch (525/520).

the pitch is the distance between the pins.
what makes the difference is o-rings.
the rubber o-rings sit between the inner and outer plates on each side of the chain,
they are approx 1.5/2mm and with one on either side of each pin.
that's approx 3/4mm wider than a non o-ring chain of the same pitch.

so if you have a 520 o-ring chain at 25mm wide, then a 520 non o-ring chain would be 21mm wide.


besides all that o-rings sap power and are irrelivent if you look after your chain properly.

might i also add that when i bought my bike it had a 180 supercorsa and 180 diablo rain,
i ran both tyres with a non o-ring chain and had no rubbing (standard rear wheel and no spaceing kit either).

i bought a new chain (o-ring) and that was the first time a chain came into contact with the tyre.

ps. i could not afford tyres for my first season and had to use what came with the bike.
i now run 160's on the rear

True but a 520 has to be marginally narrower as a 525 o ring touches and a 520 o ring doesn't, and that's on the same bike/tyres etc

[mo haggs]

same chain make?

No just ditched the shagged 525 for 520 renthals so that's probably why.
