I highly recommend the TRX450ER or 450R. The only difference is electric start on the ER. If you read all the reviews of these 4 quads, They rank them Yamaha#1, Honda#2, Suzuki#3, and Kawi is a respectable 4th. It is very close between the 4. I'm 6' 2", the honda is best suited for a taller rider than the others. The reliablity for Honda is still there, I have not seen a single problem and I ride the piss out of mine. The stock shocks are made by Showa, not top of the line but by all means they are great. I have just an after market exhaust for now. Made by 2 Brothers. Any other questions, fill free to ask.
