What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I mainly use my bike on the off-road setting, but occasionally road it down the highway. It so happen that on the evening of the 27th of august I was traveling down the highway for about six miles when my motorcycles started to make a clicking noise somewhere in the engine area.
Internet forums such as thumpertalk have pages of documented other failures of the exact same description under the 450x "transmission failure" thread. The conclusion of those who are mechanically knowledgeable and the owner's in australia is that you have to run a quart of transmission oil to lubricate these gears.
On dec 17th I receive the license plate for my motorcycle honda crf450x in order to complete the dual sport kit and be road legal. On this same day I had changed both the transmission oil and engine oil according to the honda manual. This was the 2nd change in 175 miles since it was new.
What to check before buying
- Powertrain. Shift quality under load, harsh shifts, transmission codes, CV joints.
