I used to ride strictly yamaha's but found a good deal on a 05 ski doo and bought it. I'm riding with a 03 RX-1, 02 Viper, and an 06 600 Polaris. Most of our riding speeds range from 35-45 in the turns to 55-65 mph on the rough stuff to 80-90 mph on the smooth straight shots getting air on any hill that we can.. Should I do some upgrades to this 500ss, or ride it a and go from there??
