It could be a concern... but I love mine. I put 20 hours on it in 3 days last week... then I got on my 660 raptor yesterday. I dont regret purchasing my XX at all.
On the same stretch of field, my piped/jetted/air filtered raptor did 64 mph. My totally stock XX, heavier yes of course and little bit bigger motor did 64MPH too. Im happy with it. I will ride it till I pay it off and see what happens then, Im not going to worry about it now.
