| Very interesting chart Shazaam.
3% waterwetter is not a lot in terms of absolute quantity, maybe the rider had a higher percentage mix. Even so, from the level of detail I can read on this chart on my screen, it actually looks like 3% waterwetter is gripier than plain water - can that be right?
Looking at the chart, I notice the further down the chart, the less relative friction at static, but interestingly, the gap between static and dynamic grows. Why is this? What is it about friction that makes it less grippy? What is the effect of cold/warm tyres? What would happen if your mix was say 50% waterwetter.
Either way, it's not allowed in the UK.
Kev - you're making me think now!!! Should I drain my bikes then? They're in my garage attached to the house, I'm not sure if it ever gets to freezing point out there. although it does get friggin cold - too cold to work out there without the heater on. Think I'll do it to be on the safe side.Thanks for the advice, hadn't thought of it. Come to think of it, we leave bottled water/beer etc in the garage and I've never seen it frozen up!! Maybe the heat of the house keeps it above freezing point???? I don't know, better safe I suppose.
