I buyed a used KSl 150 three years ago, here in Italy. I saw only one other like mine here in Rome. Certainly they are no well known and it´s a pity because it´s a very comfortable bike, perfect for city and travel; doesn´t runs, in fact the maximum speed I reached is 95 km/h, but it goes 50 km for a fuel litre and that´s real!!! It has no thunder sound - we bikers love it...- is silent and soft but when in the traffic it starts and moves very fast. I have no garage so it stay outside under a cover but, after six years of life there are very few points of rust, and almost all in the zone of the carrier of the front fanal that´s difficult to reach to polish. My advice? A great and cheap bike!
