they have a difrent tread and are made with a dif compound that suits sport bikes better the the tourers. very similar but (not better) but better suited.

As long as the tyre has a confidence inspiring characteristic you can't go wrong, some of the battle axes are great, infact you will find at an entry level you won't be to worried about the best rubber, you want to "read" the rubber after each ride and see how you are riding.

How did you enjoy Roys Hill? Nice track aye

The 250 rules look like they need street tyres so no 125 slicks for them

I just stick with my post classic bike,
and get my bucket fixed , nigel keeps asking were it is lol

My old RD350LC road bike bike(standard, original except for air box and jets) is 149.5 (weighed at kart track) and i just switched to reserve pulling in the gate, 17ltr tank(it needs it) i spose it would have had 2 litres for reserve, so 165kg full i guess,

theres nothing extra on the race bike lol, and its still a standard engine, makes a big difference a 30kg diet tho

180kg , i think my Duke is about that weight , there a heavy race those koreans

You would watch BT39s wearing out for road use, good choice with the 45s
