I'm currently running an Avon SM (speedmaster) II on the front that's due for replacement and would like any reccommendations on what to get next. I've only managed to get just over thirty thousand on the current one and am rather pissed off at the performance. No matter what I do I can't get it to wear right to the edges. When it's new, it's worse, I can only get about a third of the tread to make contact with the road. As it nears the end of it's life it gets better (up to three quarters) but I suspect that it's only because the profile becomes overly square. The guys at the sports performance shop snigger behind my back when I ask so that's why I'm asking here. It's not that I don't trust them or anything. They once diagnosed a persistant problem I had when running Optimax. They told me it was fouling my plugs and, sure as shit, on the way home I heard a definite 'cluck cluck' coming from under the petrol tank. As per their suggestion I now only run unleaded. It rattles a bit now but they tell me it's because of the rattle snake oil Caltex adds at the refinery. Good stuff. So good in fact that there's no way you'll ever find it on sale to the public! I mean, these guys know their stuff. They've all worked for the most reputable shops in Australia - Peter Stevens and Frasers! Anyway, they tell me that I need to ride more twisties. I tried to explain that no other Harley has _ever_ passed me on the Old Road. If that wasn't enough to get them guffawing you should've heard them after I said I've never, ever scraped it around a corner! Mind you, it was a Friday arvo and I suspect they were on more than just the usual Tooheys Lite. So, suggestions please folks. I get an easy 80k outta the rear. No way I wanna fork out 0 for a front that only gets 30k, tho' if I could get it to use all the tread that may be acceptable.
