2006 trx 450er. Stock motor, sparks full exhaust, elka legacy series shocks, and many more boltons!!
I was going to say smaller sprocket in the back too. Not sure about the front tho. Might take away to much out the hole, but I’m no expert. I think the stock sprocket sizes are the same for ltr and trx, if so is it just the EFI that gives the ltr the edge? Or gearing too?
