Hi everyone! Glad I find the forum! So for Christmas I picked up 3 new dirt bikes for myself and my two sons. I picked up myself the Yamaha TTR-230A (it's new, but a 2011), my 12 year old got the TTR-110E (new, but a 2012) and my 8 year old got the PW50D1(new, 2013). I've ridden bikes since I was 9 years old, I'm 40+ now. Rode everything from go-carts to dirt bikes to street bikes. I had got my WERA license and was on the quick path to get my AMA Road Racing license until I was laid up for a long time after a pretty bad accident and after road racing for a few years back in 1989 - 1990 (Black Ninja ZX-7) hung it up. This was the time frame when Scott Russell and Doug Chandler road for Team Muzzy! That was a great time! Anyway, I had a few questions and would appreciate some feed back. Thanks. 1) Local shop suggest not getting boots for my boys (8 & 12) they suggest that getting ankle covering boots form Meijer would work better, he said the boys might find it hard to shift with them on and they would come almost up to their knees and it could cause more knee issues then it would not to have "riding boots". 2) I was think right off the bat of putting a high performance exhaust on and maybe even changing the rear sprocket to a taller one to gear it down for better throttle to wheel response and to make it a bit edgier. 3) Was looking for a 3 rail trailer for the bikes but a few people I know told me to just pick up a flat utility trailer with a ramp and use it as I'd have more options to use of the trailer. Any suggestions on the above or other would be appreciated!
