Jota Tyre size

[Mole87]

Hi, just purchased a 1981 series 2 Jota
It has a 110 tyre on the rear and 100 on the front. I think it should be 120 rear, but has anyone upped this without affecting the handling? I was hoping to go at least 130

What size is the rear rim?
If it’s a 2.5” then you can run a 120 or, potentially, a 130.

Thanks, I’ll check

Bigger isn't better.

The 2.50" rear rim will accept a 130 tyre, but they are a bitch to fit and add nothing other than bragging rights. The chicken strip will out you as a lousy rider and your tyre fitter certainly will not invite you to a beer. Although the RGS was originally fitted with a 130 on a 2.50" rim, there is no technical reason for this. Same speed and similar load ratings as a 120... a 120 works way better. It offers a flatter profile resulting in a larger footprint using almost the entire tread width when cornering.

A 130 tyre requires a 3.00" or larger rim to be fully exploited.

After all, you pay for ALL the tyre, why only use half of it?

I bought a 750 Four Honda. I corner using all the road. After all, I pay for it.

I'm thinking that the Z1 owners need to hear that ....... they will be proud of the way their bikes handle knowing that they are using ALL of the road they paid for .....

Hey, I loved my Z1 and did heaps of ks on it. The Laverda handled and braked heaps better but I still have a bit of a craving to own a Z1 again.

I can tell you that my 81 S2 has new Avon Road Riders 120/90 on the rear and they are excellent !
