    Race tyre experiences

    that's interesting. That's great. So can I ask ...Do you run at one track only? Can you tell us what the hot mix is like on the tracks where you run? what sort of track/ambient temperature ranges do you get when racing? Are the tracks high load long duration tracks or low heat?

    Race tyre experiences

    last year i put a talented young guy on my zx10r to race in the state road race championship. this kid has spent his whole life racing bikes with NO suspension adjustment. this kid has gotten used to using his body to make the bike do what he wants or it needs to get it around the track quickly...

    Race tyre experiences

    just for example we simulated start position weight. we tried all sorts of different techniques including dirt track stances and the one that put the most weight on the front was chest on the tank. You should have seen this kids starts. He was beating 600cc bikes to the first corner every race...

    Race tyre experiences

    there is plenty of good info out there John when you're watching closely. The interesting thing was that before we went up for the tyre test mentioned above i took some scales around and we weighed the bike with rider, without rider, increased preload right thru to no preload, weight entirely...

    Race tyre experiences

    For those interested a team I have been helping out just did a test day comparing the pirelli 150/60 SC1 to the Pirelli 140/70 SC2. The track is not very long and has a very open pebble surface (so not high grip and its not a high load track either) and track temp was only 32 degree Celsius...

    Racing Fuel Cap for 2017 RC 390

    I just ordered a driven fuel cap from the powerparts section from commonwealth for my 2017 and they said that it only fits the 2015/2016 models. so they refunded me However I have seen listings for race caps for 2015 thru to 2017 as being the same. so I'm confused.

    Why does my rear tyre slide out so often?

    There is something that not many riders will actually admit to and don't normally talk publicly about it....it may be a contributing factor here....it's called "premature acceleration". thankfully there is a cure...you need a kind caring understanding motorcycle.

    Race tyre experiences

    Just BTW, at the last race meeting I was talking to a guy who runs pirelli's on his bike (non KTM) and he was saying that he wasn't happy with his previous suspension guy so he changed to another professional suspension guy. The new guy changed quite a few things ( wouldn't say what...I think...

    Race tyre experiences

    ok the first thing is that you must always talk "hot" pressures. This is important because the internal pressure works hand in hand with the tyre construction. It is important because the pressure controls footprint size and shape and supports the loaded area to help prevent distortion of that...

    Race tyre experiences

    Ok I was going to be gracious and just leave it at your attempt to explain how heat was generated by a tyre. After reading that attempt I realised that you obviously mean well but you haven't got a clue. I felt that it was best not to antagonise you any further because I realised that it was...

    That's exactly what I would expect from you. You say you want to help people and yet you won't explain even the fundamentals of tyre performance. So far you have twisted things that i have said and behaved like a troll. All due to your ego. I'm sure a lot of people here have no idea how a tyre...
