quick question and i'm pretty sure i already know the answer....

650 rear rim is a 2.50. i presume this needs a 120 tyre?

reason i ask is i have the same size rim on my 11 and that has a 130 on it... i'm thinking my 11 has a narrower rim than it should have (maybe it's off a GS1000) somewhere along the line as it's quite a bit wider than the rim.

so... 650 should use a 120 tyre on a 2.5 rim and my kat rim is too narrow for a 130?

thoughts please gents

I have a 130 on my 650 and a 120 on my 1000......yeah I know......So either will do!

So... If you were to buy a new tyre for a 2.50 rim you'd buy what? 120/90 as there'll be a load less tyre bulging off the rim?

My XJ600's have a 2.5" x 18" rear wheel, standard tyre size is 110/90/18.
Here's a Dunlop spec/conversion chart. it says either a 110/90 or 120/90...The original tyre for your bike was a 4.25 x 17. http://forbes.sprint3.com/package/webse ... rce_PK=221" onclick="window.open(this.href);return false;

Think i'd go for the 120/90/17.

I was thinking the same bud.... Makes sense to me. Cheers for that, I'll get a 120 on order I recon

And dont forget 120 /90-17 are a bit cheaper than the 130/90-17.................what you after getting, a BT45?

Road rider cos I already have matching front laying around..
