JT SPROCKETS Front Sprocket 14 Teeth for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 2018-2026

The JT SPROCKETS 14 dents JTF1905.14 front sprocket is designed for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 from 2018 to 2026. 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.

Specifications

• Brand: JT SPROCKETS
• Manufacturer part number: JTF1905.14
• EAN code: 824225209198
• Material: steel

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.

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.
