On my other bike I have decided to try a top road tyre,Bridgstone BT090,s. I already use these on my Honda NC35 and seemed to work well at last years Mallory bonanza. My next outing with both the race bikes will be at Snetterton 28th/29th this month. It will be interesting to test both tyres out on similar race bikes. This is the nice new Bridgstone fitted to the NC23 so it will be interesting to check the side wear next time out.
I just hope the grip level on the road tyre is as good otherwise I could be testing out the strength on my leathers!
