The pistons should last the life of the engine, just keep your car maintained and use decent fuel and all should be well mate

lets not forget to mention using the correct oil is a major contributor to the life span of the engine

The forged pistons should be changed out every 10k miles at every service generally.

No worries, will post up some pics of the bike, don't have many photo's, but be lots more when the weather gets warmer,
more of a fair weather rider to be honest, but still go out with friends if a nice sunny day, what bikes have you had Zany?
