Chromoly high tensile steel 520 size Compatible with: CBR250RR (all MC51 models) Number of teeth: 42T (normal: 41T) A speed pulse unit is required when changing the number of teeth

●Recommended for setting and repairing CBR250RR '17 (MC51). ●Normal number of teeth: 41T ●Number of rear sprocket teeth ÷ Number of front sprocket teeth = Reduction ratio The larger the number of this reduction ratio, the more emphasis is placed on acceleration, and the smaller the number, the more emphasis is placed on maximum speed. Precautions for use ●Sprockets are consumable items. As a guideline during general driving, please inspect the sprocket every 1,000 km. If the tooth tips are tapered, replace them. Daily lubrication will greatly improve the life of sprockets and chains. ●A separate speed pulse conversion unit (part number: 762-1840100) is required to correct speedometer errors that occur when changing the sprocket number combination or tire size.
