BOYESEN reed valve replacement Pro Series BOYESEN reed valves system for KTM, HUSQVARNA, HUSABERG and YAMAHA 1999-2017

BOYESEN offers these reed petals for KTM EXC 250, EXC 300, FREERIDE 250, SX 250, HUSQVARNA TC 250, TE 250, TE 250 I.E 4T, TE 300, HUSABERG TE 250, TE 300 and YAMAHA YZ 250 1999-2017. In the reed valve, thin reeds open to let the mixture in and close to stop it coming back out.

Why replace the reeds?

The benefits:

• Get the performance of a new reed valve back for little money.
• Lightweight material (often carbon) that reacts quickly.
• Quick replacement without changing the whole reed block.

Why choose BOYESEN?

Boyesen invented the dual-stage reed: a soft petal for low and mid revs, a stiffer one for top end, for more torque everywhere.

When should you replace the reeds?

A petal that no longer seals, or that is split or frayed, must be changed straight away: a piece drawn into the engine can damage it.
