The chassis updates—namely the new frame, swingarm, linkage ratios, and suspension valving—mean there’s a lot more going on than meets the eye. I’ve been somewhat critical about the current generation of CRF450R as it has been a bit of a love-hate relationship. The bike has a chassis that’s hypersensitive to any change whether it’s engine, suspension, gearing, or just about anything else. When everything is going well, this bike is very exciting and fun to ride. However, when you get into trouble or make a mistake, it can put you on the ground fast and hard. I’ve spent several hours on the CRF450R during the past two years. Over that time, I’ve tried a number of chassis parts and suspension settings. While some improved the bike’s handling, nothing really cured the bike’s unpredictability when you make a mistake.
