MOTO-MASTER Ultralight Front Sprocket for HUSQVARNA CR, TC, TE, TXC, WR 1990-2013

The MOTO-MASTER front sprocket is designed for HUSQVARNA CR 250, TC 250, TC 450, TC 510, TC 570, TC 610, TE 310, TE 350, TE 400, TE 410, TE 450, TE 510, TE 570, TE 610, TE 630, TXC 250, TXC 450, TXC 510, WR 250, WR 300 from 1990 to 2013. The front sprocket drives the chain at the gearbox output. Small and working hard, it wears faster than the rear sprocket: it's also the simplest way to change the bike's gearing.

Choosing the right number of teeth

Start from the stock number of teeth. One tooth less on the front sprocket shortens the gearing (more acceleration, ideal on tight terrain); one tooth more lengthens it (more speed on fast tracks). One tooth on the front sprocket is worth roughly three to four teeth on the rear sprocket.

When to replace it?

• Teeth thinned, pointed or hooked.
• Chain that jumps or slaps under acceleration.
• Play between the sprocket and the shaft, or marked splines.

Check it every time you service the chain and replace it along with the rear sprocket and the chain. Many riders change the front sprocket with every new chain, because it wears much faster than the rear sprocket.

Fitting tips

1. Loosen the sprocket nut or bolt while holding the rear wheel with the brake, before slackening the chain.
2. Clean the countershaft and check the oil seal behind the sprocket.
3. Fit the sprocket the right way round, with a lock washer or threadlocker as on the original assembly, and tighten to the manufacturer's torque.
4. Set the chain tension and lube it with chain lube.

Why MOTO-MASTER?

In motocross, Moto-Master was working with the Red Bull KTM Factory Racing team as early as 2010, and it backed the MXGP world championship in 2015. On the technical side, the Flame profile of its discs is designed to improve cooling and go easy on the pads, and its Racing GP sintered pads use a backing plate with hooks (NRS technology) that stops the friction material from coming away.

Frequently asked questions

Should the rear sprocket be changed too?
If it's worn, yes: a new front sprocket running on a tired rear sprocket and chain is worn out within a few hours.
