Description

If your Yamaha WR450 or WR450F is clicking but not cranking – or just giving you a dead silence when you hit the starter button – that starter solenoid relay is often the problem.
This little electrical component is what sends power from your battery to the starter motor when you press the button, and over time the contacts can burn out or stick.
This one from FELLERS SMALL ENGINES is a brand new replacement that fits the 2009 through 2012 model years – also works for '09, '10, and '11, and likely '12 as well.

It's a simple but critical part for anyone who rides off-road or on the street – when this fails, you're either bump-starting or walking home.
Installation is dead simple: locate the relay (usually near the battery or under the seat), disconnect the two big battery cables and the small trigger wires, bolt this one in, and reconnect.
Takes maybe ten minutes with basic hand tools.
Just be mindful of the California Prop 65 warning – pretty standard for electrical parts with solder or copper.
