Let me caution people here: these new Triumph twins come with cast pistons and steel con rods! The old 650's had forged pistons and forged aluminum con rods, so they could take the high rpms.
Revving the snot out of a cast piston engine is just asking for trouble, as in "It got blowed up!"
But, if one installs a Wiseco big bore kit, one gets replacement forged pistons, which are certainly strong enough to survive high rpm blasts.
Hmmm......that sounds worrisome looking at it from this perspective....if 1000 more RPM's would make the top end unreliable in what would be a catistrophic failure, then 1000 RPMS less (stock limiter) doesn't make me feel too reassured about my stock engine. In other words, how reliable is the stock setup if increasing the rev limit by 1k risks catistrophic failure !?
