Gearing?

Thats about as fast as the 15t. I would change it.
One more thing, my fuel compsumption remained the same with the 14t, with pillion and luggage at 120/140 km/h I just have to refill each 300km (18l tank). I do not know why is it but I was surprised. Maybe because althought the bike is revving the throttle is more closed.

nah, don't like it revving it's tits off at 100, 8k is okay though. As my commuter, it suits me the way it is.
