The ProTaper CS4 KTM 505SX Rear Steel Sprocket - 37 Teeth is a rear sprocket built from high-strength 460 steel and finished with ProTaper's KTL coating to resist wear and hold up over time. The teeth go through a diamond-cut process that ProTaper says results in hardness 25% greater than standard, which translates directly to longer service life. This sprocket fits the 2009-2010 KTM 505SX and 2009-2010 KTM 450SX, making it a solid choice for off-road and motocross riders who put hard miles on their drivetrain.
A 37-tooth rear sprocket raises or lowers your overall gearing depending on what you are replacing. Moving to a larger rear sprocket lowers gearing, giving quicker acceleration at the cost of top speed, while a smaller rear sprocket does the opposite.
