Maybe the smile on your face and the fact that ownership of a 625 makes you a member of a more exclusive club - 640's are much more common. On a 12 mile journey the tyres will hardly have warmed up (if its through urban traffic) so your question is maybe a tad academic?I know the 625 is slightly more balls out, but in real world driving (12 miles each way) how much difference would you notice?
What are the key differences?
625 does have a balancer shaft, the difference between a 640 and 625 is just the smaller tank, Keihin carb and SXC end can for pre 05 models.The 625 does,nt have a Balancer Shaft, so slow speed vibes are the big difference. Around town commuting at low speed the 625 gives ya mental eyeball vibration and numb hands, whereas the LC4 640 feels much softer, in my experience
625, 640, 660 or Duke II - I'd just buy the best condition one that you can source for your budget - unless you absolutely need an electric start or hate the looks of a particular model.Some great advice here, so widening my search out to a 640 is not such a bad idea?
Yip it's that time of the year (happens regular as clockwork) when KTM need to clear out their stocks of unsold bikes ...... and every year some muppets still insist on paying full list price!There is £1250 off the price of 2010 690 SMC's at the moment, why not whack a bit on finance?
