It's a good sled, i'm 18, i have one. I drive it pretty good, 6000 kilometers no trouble at all. Good on gas, not too expensive, great sled for the trails. It has 70HP. May not sound like a lot but with it only being 430 pounds it goes great on the trail. Top speeds 88.5 miles per hour (Sled is geared for bottem end for trail). Great bottem end, snappy throttle. GREAT handling, just like all the other REV's. I'm putting a silencer on mine soon, so if you want it to sound great, talk to jonny at www.sled-x.com, he will have one available soon for the 550. Good luck. If you have any other questions leave me a message and id be happy to helplooking to buy a 550x for my 16 year old brother. want some input on the sled. power?? what can you compare it to.
