Renthal – Front Sprockets - Other, including sprockets for the 2026 Ducati Desmo450 MX, 2024 Triumph TF250 X, BMW S1000RR and S1000XR, Royal Enfield 350 singles and the 87-03 Honda CR 125R, not every machine fits neatly into a Japanese-badged aisle, and this is where the rest of the garage gets sorted. It gathers countershaft gearing for newer and less common platforms, including the Ducati Desmo450 MX in both standard grooved and Ultralight grooved form, the 2024 Triumph TF250 X in 515 pitch, the 17-23 Ducati Monster 821 and 937, Supersport S, Hypermotard and Scrambler in 525, and the 19-and-later BMW S1000R, S1000RR and S1000XR in 520 counterweighted form. Tooth counts run from 13 to 16, so riders can shorten gearing for corner drive and technical riding or lengthen it for relaxed highway rpm. Hardened steel and tight pitch tolerances keep the chain running smoothly and quietly, which extends the life of the whole drive set. Renthal applies the same racing-derived material and finishing standards across these fitments, so unusual machines get the same crisp throttle response as mainstream race bikes.
