How much horsepower does a 250r have?
39.4 hp
Powering this Japanese motorcycle is a liquid-cooled, DOHC, four-valve, 249cc four-stroke engine. We ran the CRF250R on our rear-wheel dyno to determine peak output from Honda’s 250 four-stroke motocross bike. We documented 39.4 hp at 12,300 rpm and 18.8 pound-feet of torque at 9,700 rpm.
Do sprockets increase torque?
Changing your rear sprocket won’t give you more mid range or change the engine power curve in any way. It will alter the torque at the rear wheel at all RPMs. The bike should accelerate faster through the gears but you will also loose out on top speed. You don’t need to get dyno tuned just for changing a sprocket.

How do you pick a sprocket size?
Sprocket Ratios This is determined by the the number of teeth on the front sprocket, compared to the number of teeth in the rear sprocket. For example, a motorcycle with a 17-tooth front sprocket and a 45-tooth rear sprocket would have a ratio of 2.65 (45 divided by 17 = 2.65).

Is a 250R faster than a 450R?
Dollar for dollar, they are both excellent choices. In some places—like the pocketbook—the 250R does perform better than the newer 450R. And maintenance-wise, the two-stroke 250R is a lot easier to take care of than today’s technologically advanced four-stroke.
