If you're riding a Honda CR250R, CRF450R, TRX450R, or similar models, this Supersprox front sprocket is a legit upgrade. It's built from SCM-435 carbon-free steel and has an ultra-hard surface layer to reduce friction and chain drag — meaning less power loss and longer life. The design includes radial holes to keep it lightweight, plus grooved teeth that help kick dirt out fast (super handy for off-road riding). This is the same kind of spec used by factory racing teams, so you know it's tough. Fits a bunch of Honda bikes from the '80s up through recent years — check the list to make sure it matches your model. Easy to install and built to handle serious riding. Whether you're hitting the track, trails, or just want a durable replacement, this sprocket delivers performance you can count on.
