IDK but the jump from complete stock to a quality exhaust, ram air, tune, and cat delete, BIG difference and that is from like 145hp to close to 160! you will never be displeased with the 210 build, the curve is SO MUCH HIGHER across the board, BUT if you a DIY guy, the cost is basically the same from 210 to 240 and its not that much of a bump but its going to be 2 different bikes due to the torque curve. If you have the $ and are going to have carpenter or a qualified mechanic shop do the job, i would just stick to the 240 due to the tiny difference in cost, you can always tune it down a bit from the 240 but you cant tune it up from the 210. If you have absolutely ONLY the budget for the 210, its NOT a deal breaker, its going to be an insane fun motorcycle. Just have the trans redone by robertsons with a solid 4th gear either way.
