My son is an aggressive novice rider. Weighs about 120. He is having a real difficult time keeping the rear wheel under him on whoops, braking bumps and sometimes on flat landings. I got an email from RG3 the other day about their linkage resolving these issues. I am not even sure they make one for the 150R yet. But do any of you have any linkage mods you can share? Or anything else that might be helpful in keeping that rear wheel under him. I would be most appreciative.
