Avon Roadrider question?

[Footy.]

Hi Folks.

It's getting close to new tire time now on my 78 GS750E (alloy wheels) I hear good reports here of the Avon roadriders, and will probably go for them.

From other posts, the sizes refered to for my bike seem to be 100/90-19 front, and 120/90-18 rear.

Refering to Avons PDF spec for the roadriders here :

According to this the rim sizes on my bike are one size smaller that avons minimum recommendation for these tire sizes. The view here seems to be that this is OK.

Now i notice on the Avon specs that the 130/80-18 tire rim recomendation is the same min/max as the 120/90-18.

So bearing in mind this would in our case also be one size out for our rims, would the wider 130 rear be OK to fit?

Regards.

Your rear wheel is 2.15" wide so sticking a 130 on there is really pushing it. A 120 is a much better match in my view. Bikes running 130 rear tires should have a 2.5" wheel, again in my view.

You can fit larger tires, but they tend to make the bike feel as if it's falling into a corner. Stick with the stock sizes and you'll be much happier.

OK thanks for the input folks.

I have no idea what your stock rim widths are or what the original tire sizes are, but yes, I agree that you want to stick very close to those sizes.

Wider tires often work fine on those low-tech devices with four wheels, but on advanced two-wheeled transportation such as ours, staying with the original tire sizes will preserve the correct profile of the tire and improve handling.

Thanks for the response.

The front is 1.85 rim, and the rear 2.15. As you can see from the Avon PDF, this would make a front 100/90-19 and rear 120/90-18 too wide? But these seem to be the sizes people here say are OK.

Thanks again.
