2023 Yamaha YFZ450R ATV Review: Engine & Chassis Upgrades

Introducing the 2023 Yamaha YFZ450R ATV

Yamaha has unveiled the 2023 version of their popular YFZ450R sport ATV. As Yamaha's flagship sport quad, the YFZ450R is known for its potent engine, nimble handling, and durable construction that allows it to dominate the racetrack. For 2023, Yamaha has made key improvements while keeping the YFZ450R's winning formula intact.

Evolution of the Legendary YFZ450R

The YFZ450R first debuted in 2009 and instantly made a name for itself in the ATV racing world. Right off the showroom floor it had the performance upgrades needed to be podium-ready. An advanced, liquid-cooled 449cc fuel-injected engine provides an endless well of torque and screaming top-end power. The YFZ450R revolutionized what an ATV is capable of, winning countless GNCC and WORCS racing championships over the years.

While the engine and aluminum/steel frame have seen continual refinement, Yamaha has not radically changed the YFZ450R equation. It still packs the most powerful sport ATV engine in production. And its race-tuned chassis gives it unmatched maneuverability and razor sharp handling.

2023 Yamaha YFZ450R Engine Upgrades

The motor that has powered the YFZ to the winner's circle for over a decade gets key enhancements for 2023. The 449cc liquid-cooled 4-stroke engine maintains its potent power delivery but gains improved control and driveability.

Fuel mapping revisions optimize the fuel/air mixture for enhanced throttle response and power delivery across the rev range. New cylinder head porting further increases the breathing efficiency for more power. Larger 40mm throttle bodies, new Denso 12-hole fuel injectors, and an updated EXUP exhaust valve yield more immediate throttle input.

In the transmission department, a new clutch lever ratio provides a lighter clutch pull for reduced fatigue. The refined engine and updated transmission combine to offer snappier acceleration and a more connected feel for the rider.

Chassis Upgrades for Precise Handling

YFZ450R owners will immediately notice improved handling and cornering confidence from the updated chassis. The front and rear suspension receives upgraded spring rates for a more progressive, controlled ride. This allows the 450R to better absorb impacts while also resisting bottoming over rough terrain.

Further enhancing agility and cornering precision are the all-new Maxxis Razr MX tires designed specifically for high performance sport ATV use. With a rounder carcass profile and optimized tread pattern, these tires cut, grip, and track through turns better than ever.

Ergonomic changes include a redesigned seat with deeper knee pockets to better secure the rider during aggressive riding. Yamaha also shortened the handlebars by 10mm for a more compact riding position to enhance maneuverability.

YFZ450R Special Edition Released

Alongside the standard 2023 YFZ450R, Yamaha has released a Special Edition model featuring exclusive graphics and accents. The 2023 YFZ450R SE stands out with dark metallic gray and lime green plastics. Color matched beadlock capable wheels look right at home with the aggressive SE graphics kit.

Special Edition models feature wave rear brake rotors and anodized rear grab bar and shifter. Of course the SE still has the potent, bulletproof engine and podium capable chassis as the standard YFZ450R.

2023 Yamaha YFZ450R Pricing

Considering its professional grade performance pedigree, the 2023 YFZ450R represents a good value with an MSRP of $9,599. That nets a buyer the most powerful and race-ready sport ATV that Yamaha offers straight from the showroom.

Opting for the Special Edition graphics adds $200 to the price tag. So buyers can expect to pay roughly $9,800 for the privilege of owning the limited YFZ450R SE model. Still, that remains very competitively priced against other high-end sport ATV contenders.

While common for racers to throw on tons of aftermarket parts, the YFZ needs little to make it race ready. With minimal modifications like an exhaust, programmers, etc. it can start vying for podium finishes immediately.

Dealer Inventory Arriving Now

After the 2023 YFZ450R and SE reveal in June, many sport ATV fans have eagerly awaited their arrival. The good news is the wait is nearly over as Yamaha expects the new models to reach dealerships starting in December 2022.

Demand and supply chain issues could make inventory scarce initially. So interested buyers may need patience as production ramps up to meet demand. But Yamaha seems confident shipments will catch up in early 2023 barring any further supply constraints.

There’s nothing quite like the YFZ450R in terms of straight from the crate performance. So buyers itching for a new toy to tame trails or tackle the track will find the 2023 updates well worth the wait.
