I would trust Gen 2 mileages more than Gen 1's. After 100,000, kms or miles, Gen 1's just start over at 0 mileage. I see a lot of extremely low mileage bikes that have aftermarket exhausts, LEDs, boost not working, 2nd gear problems, etc. that I can see are just not low mileage. Just a warning to buyers and sellers. Look very close before buying any old, carbed bike.
