GPR Camp: Replica Racers

Anyone have a clue on how to find decent sport tires for a GPR with 16s?

They are tiny - 90/90-16 front, 120/80-16 rear. I have Avon Vipers on it now, but they are too big, not real grippy, and old.

I'm not finding much in a sport tire.

Thanks!

As an update, I have found a few options, but no 90/90 - 16s -

Bridgestone Battlax BT46F
100/90 - 16
120/80 - 16

Pirelli Angel
100/80 - 16
120/80 - 16

Mitas Touring Force SC
100/80 - 16
120/80 - 16

I'm probably going with the Mitas SCs. They are significantly less expensive than the others. I do like the 80-series profile better than the 90, and a 100 will fit. I have a 100/90 Avon Viper on there now - but it looks too tall. The 80 would be shorter.

I spoke with a company that will be ordering Mitas tires soon (sometime around 4/26).

I feel your pain. The only 90/80 - 17 I can find is the Michelin. And Im not super excited about its feel.

I suspect the sidewall profile is different than ours but inch measured moped racing tires might be an option. It gives us more options on compound at least.

90/90 - 2.75/3.0
100/90 - 4.25/4.50
120/90 - 4.25/4.50
120/80 - 4.25/4.50


* If ToroToro is around this should be a triggering post. He knows a LOT more about the GPR tire situation that I. And has a better understanding of tire profile on performance and handling.

There used to be more options.

Mitas made sport tires in 16" that ToraTora had on one of his bikes, I think, but they are no longer in production.

He actually switched one of his GPRs from 16s to 17s to get better tire choice, among other things.

I'm still waiting for a gasket set from Treats. It's been almost a year.
