I am curious to see some top speed #'s. Pavement, dirt, grass, no matter. I have an 09 O/L Max 13 hrs and 220 KMS (approx 140 miles) took it for a good run this afternoon. There's about a 1/2 mile stretch of pavement leaving my driveway, heading to the nearest trails. I run 27" mudlites 9's front with 5lbs of air and 10's back with 4 1/2 lbs of air, stock suspension, set up on first click all around. Got up to 110 kms (68 mph) real quickly, but that was it. Tires may throw speed off a few clicks but was pretty topped out. Heard lots of stories of these things running over 130 kms (approx 80.6 mph), maybe it was the 1 up model. Not really a speed freak but you got to love a good rip to the top end. Lets see what u all got. Could be a fun topic.
