This Bike was Adult ridden by a 55 yrd old. Bike only ridden in South Florida and never seen rain. All services have been with BMW/ oil was always changed early. Rider is 260 lbs and the bike is super quick with that size of rider. I've been riding streat and dirt bikes since 1967 and this is without question the best bike I've ever owned. It feels like its on rails in a corner and like explosive lighting on the straght away. Also Quick shift really makes the bike performance out of the corners onto a straight.
