Comparison: Yamaha YFZ450R vs. Competitors
The sport ATV market has dwindled, but the Yamaha YFZ450R remains a standout. Let’s compare it to two former rivals: the Honda TRX450R and Suzuki LT-R450.
Yamaha YFZ450R vs. Honda TRX450R

- Suspension: The YFZ450R’s KYB shocks with Kashima coating outshine the TRX450R’s Showa suspension in adjustability and smoothness.
- Weight: The YFZ450R (405 lbs) is slightly heavier than the TRX450R (380 lbs), but its lower center of gravity improves handling.
- Price: Used TRX450Rs range from $4,000–$6,000, while new YFZ450Rs start at $10,299. The Yamaha’s modern tech justifies the premium.

Yamaha YFZ450R vs. Suzuki LT-R450
- Engine: The LT-R450’s 450cc engine is fuel-injected like the YFZ450R, but its power delivery is less refined, with a slight edge in low-end torque.
- Chassis: The YFZ450R’s aluminum/steel hybrid frame is lighter and more rigid than the LT-R450’s steel frame, improving agility.
- Availability: Suzuki discontinued the LT-R450 in 2012, making used models ($4,500–$7,000) harder to find than the YFZ450R.
