We take a lightly modified Yamaha YZ450F and put it to the test at North Carolina’s muddy Steele Creek GNCC. See the full details in our 2011 Yamaha YZ450F GNCC Race Test.
- The YZ450F proved capable of winning against determined amateur competition. Further delving into the off-road potential would only make this bike better.
- This was definite the type of terrain for Dunlop’s MX31 soft-terrain tires.
- Braking Batfly 270mm oversized rotor was a welcome addition in sloppy conditions.
- We picked up an invite from Yamaha to try out a nearly stock YZ450F at the Steele Creek GNCC in North Carolina.
- IMS does a great job of keeping the YZ thin while offering 2.4 gallons of fuel.
- For extra control, Yamaha installed a set of medium compound slim grips with half-waffle design ($10).
- The Stealth DX ($50) is a flag-style guard that mounts using 6061 T-6 aluminum mounting bars with plastic shields and flexible rubber edges.
- Using stock suspension, we deferred to Whibley’s mechanic, Scott Brooker for settings.
- Plowing through mud and lugging up slimy hills was much easier with the additional flywheel weight. This was definitely our favorite upgrade.
- Things went from bad to worse as I stalled twice and crashed four times in the first 1.5 laps. Suffice it to say that I labored through the opening laps until reaching the gas stop.
- This project goes to show that even normal guys like us can enjoy motocross and grueling off-road on the same machine.
- The Dunlop MX31 tires were charged with finding traction in deep mud, wet rocks, slimy roots and even slippery wooden bridges.
- With the bike prepped by Yamaha's factory GNCC team, there was nothing left to do but sign up for two hours of mud and suffering.
- GYTR has teamed with FMF to offer multiple exhaust options for the YZ-F.
