Part of the reason that honda developed the 150cc was to replace the 2 stroke 85cc although I don't know if it has been as successful as they would have hoped as the idea was for them to race against the 85cc and in America they don't allow that as they race in their own class. Australia has them racing against the 85cc.

Just go along to a dealership and have a sit on a few different bikes to judge how big a bike you can manage. The crf150r is a really great bike and you would be able to race that for a couple more years. If you are really tall you could look at a 4 stroke 250cc.
i had a honda dirt bike before but i wanna make a change which should i get


As for racing, you need to be damm good to shine above younger and better riders.

other then that it just makes your bike nice and loud like the rest of us

Look up local tracks in your area. Two sites that have track info are www.wheretomx.com and www.dirtwerkz.com . Find out about joining up so then you can take your son along to practice days to get used to being on the track with other riders. The club secretary will also be able to give you information in regards to what licencing you need to be able to race and how to get a race number. Ask about the rules of racing and find out what all the flags mean so as your son knows what to do when one is waved at him. Also see if the club has a club coach so you can get some lessons for your son.
If you are buying second hand try and take someone along with you who knows about bikes so they can check the bike over as there is no point buying a bike and then finding out that it has major problems as you usually get what you pay for
also what to look out for when buying one

If it were me, I'd get a late-model four-stroke. The power delivery is smoother and they're easier to ride. Check out the Honda CRF250 (or at least the CRF230). Yamaha, Kawasaki, Suzuki, and KTM all make excellent bikes. Some people only buy certain brands (mine are Honda and KTM), but they are all such advanced machines that any of them will be more than enough bike for you. Get at least a 230cc, but only if you're willing to need to buy a bigger bike in a year.
For the record, I ride a 2003 CRF450. If I had bought a smaller bike, it simply would not have been powerful enough, and I'd have had to buy a bigger bike. But I've been riding for over 20 years, and so I knew I needed a big bike.
