WHICH BIKE MAKES THE MOST TOP-END HORSEPOWER?
Top-end power is measured at 12,000 rpm, though that
isn’t indicative of peak horsepower. The CRF250 could
only manage 35. 84 horsepower. The YZ250F was tops in
the class at 40. 99 ponies, but only slightly more
powerful than the Husky FC250 ( 40. 97 horsepower). The
KTM 250SXF was the only other bike over 40 horsepower
at 12,000 rpm.
The Honda CRF250 makes roughly 5 horsepower less
than the class leaders and is 2-1/2 horsepower short of
the Suzuki RM-Z250. Interestingly, the Kawasaki KX250F
falls just shy of 40 ponies ( 39. 97) in top-end performance,
yet that number doesn’t relate to the track. Test riders
raved about the KX250F’s broad and usable engine in
race situations, though it didn’t win this category.
WHICH BIKE MAKES THE MOST PEAK HORSEPOWER?
Peak horsepower doesn’t necessarily fall on even rpm
numbers but in the gaps between them. On a 250cc four-
stroke motocross bike, most MXA test riders prefer the
peak horsepower to fall at 12,000 rpm.
The CRF250 peaks at a lowly 11,000 rpm. The Suzuki
( 12,200), Yamaha ( 12,300) and Kawasaki ( 12,700) are all
within range. The Husqvarna peaks at 13,600 rpm, well
beyond where most riders are capable of riding. The
2015 KTM 250SXF doesn’t peak until 13,800 rpm. That is
the highest rpm range of all the bikes.
