When you purchase a-arms for the 2009 YFZ450R, look at Houser Racing solutions for this quad. This quad has houge caster issues. As the a-arm compresses, as it would when you are getting ready for a corner, the frame design adds caster to the steering. Adding caster makes the quad want t go straight, not corner. This is exactly opposite to how the quad should steer, in our opinion. As good as you think that this quad is working, it does not steer close to it's potential.

We have worked closely with the GNCC factory Yamaha riders to further develop two solutions. One of the solutions is the Cecco bracket used by Traci Cecco. This bracket & a-arm system is a great solution, but AMA would not allow the pro or the pro-am riders to use it. Those riders all use our Patented TRICTRAC system with a high lead spline shaft. If you are unfamiliar with the TRICTRAC, it reduces caster as your a-arm is raised.

The first race that the Houser Racing solutions were used, was at Lorreta Lynn's. Traci won her class, she had not won all year. Bill Ballance won, he had not won all year. Brandom Sommers got second, his first pro podium ever. Donie Ockerman & Johnnie Gallagher are using the setup. These are the riders that I know of. If you know any of these riders, ask them for their report on it.

If you are getting more arm pump than usual riding this quad, that should be an indication of the problem that can be corrected. This is a graet quad than can be made to handle better.

If you take your shock off the quad, raise & lower the a-arm & look at the top ball joint. As the arm is raised, it moves backwards relative to the lower ball joint.

Hope this info helps anyone who has this quad. John Houser, Houser Racing
