We recently installed Zeta Armor Hand Guards on our 2008 Yamaha WR250R and our 2009 Yamaha WR250X.
On our WR250R...
The WR250R got Zeta Armor Hand Guards (1 1/8" size) along with Zeta XC Flasher protectors that integrate the front turn signals into the plastic hand guard. We also installed a 12oclockLabs Turn Signal Running Light Adapter as well as a 12oclockLabs Fixed Rate Turn Signal Flasher to get the front XC Flasher Protectors to operate as running lights and flash at the slow factory turn signal flash rate. Since we ride this bike off-road, we installed the handguards using the optional Zeta Hand Guard Mount for Triple Clamps, which is the most secure way to mount them and lessen the likelihood of them rotating on the handlebar in the event of a crash.
On our WR250X...
Our WR250X got the Zeta Armor Hand Guards (7/8" size) with the standard plastic Zeta XC Protectors.
I had been running a Delta Barrel 4 exhaust on the WR250X project bike, and it was time to re-pack it so I thought what better time to try out a FMF Q4 exhaust system. I had already installed an FMF EFI Programmer for the fuel injection system, as well as an EXUP Eliminator, so all I had to do was un-bolt the Delta exhaust and bolt up the FMF PowerBomb header and FMF Q4 Slip-On Muffler. Installation was very straightforward and all hardware is included.
The FMF Q4 is probably the most popular exhaust for the 2008+ Yamaha WR250R / WR250X and for good reason... not only does it make the bike sound much better, but it's not overly loud like some exhausts. Don't get me wrong, it's still louder than the stock exhaust, but FMF has designed the Q4 to use intricate chambers and baffles that improves air flow while still dampening sound. It really does work and it sounds great without being deafening.
The Q4 muffler also includes a removable USFS spark arrestor, which is a must for off-road riding, and the Q4's aircraft grade aluminum and high strength stainless steel construction will also save a few pounds over the stock exhaust system.
