Good morning, I had a couple questions about a 2015 CRF 150 our. I'm looking at purchasing a 2015 CRF 150R for my son and this will be his first race bike. The owner was the original owner and said that it wasn't written but about 30 to 40 hours and was only ridden around the farm never raced. I would like to know what I need to watch out for on this bike. Its looks like It's incredibly clean and it looks like It has been well maintained. My boy is coming off a KLX 110 L. My boy said he wanted a t0 2 stroke. I moved into a KX 65 which was actually smaller (so he could get the feel of a 2 stroke) but he did not like the erratic nature of the two-stroke power band, and sold it after three weeks. I've been going back and forth back and forth depending on which bike to get him and I think I'm going to settle in on at 150R. He loves the four stroke power delivery however wants adjustable suspensions since he likes to jump. Any other recommendations and anything else I should know before purchasing this bike in a couple days?
