ATHENA Timing Chain for BETA RR 250, RR 350, RR 390, RR 430, RR 480 and TM RACING ENF 450 2005-2024

ATHENA offers this cam chain for BETA RR 250, RR 350, RR 390, RR 430, RR 480 and TM RACING ENF 450 2005-2024. In a four-stroke engine, the timing chain transfers the crankshaft’s motion to the camshaft.

Why replace the timing chain?

The benefits:

• Replace a stretched, noisy chain.
• Restore precise valve timing.
• Best replaced with the tensioner and guides for a fully new set.

Why choose ATHENA?

Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.

When should you replace the timing chain on your BETA RR 250?

Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
