First Look: 2026 Yamaha Off-Road Range Digested
Yamaha has revealed its 2026 off-road competition range of Enduro, Cross-Country and Motocross models. Headline updates include 70th Anniversary colour options, smartphone ECU locking on four-stroke models, and major upgrades to the YZ450F.
Yamaha’s latest model announcement comes out swinging with a nod to their track record and a firm message: “The pursuit of improvement and constant innovation never fades.” Winning today doesn’t guarantee winning tomorrow, and the relentless development from the Japanese manufacturer continues—though 2026 is arguably a quieter year for those who prefer riding between the trees.
Each year sees significant updates to at least one model (two-strokes often excluded!), and while MX bikes take centre stage here, the technology trickles down to Cross Country and WR models in time.
Has having Cody Webb on board, developing his own race machines, influenced production models yet? It doesn’t appear so—once again, the YZ250 two-strokes stand like blue monoliths, unchanged come rain or shine and reliable as ever.
2026 Yamaha Off-Road Highlights
- Yamaha has focused on improving performance and handling on its flagship YZ450F and boosted the YZ125’s intake and carburation.
- YZ450F gets a new engine, frame, suspension and clutch
- New chassis and upgraded suspension with larger base valve piston (28mm) and split oil passages for improved damping
- All 4T models now feature an ECU lock function via smartphone
- YZ125 redesigned intake system and improved carburation for smoother power delivery and throttle response
- Updated graphics and colour options across the m otocross, enduro, cross-country and trail ranges
- 70th Anniversary Editions of the YZ450F, YZ250F, YZ250 and YZ125
- No obvious 'Cody effect' on the two-strokes
2026 YZ450F – “Stronger Tumble in the Combustion Chamber”
The 2026 YZ450F boasts a redesigned intake system delivering smoother, more linear throttle response and better low-to-mid-range control. Yamaha says the new intake port and wall shape increase tumble within the combustion chamber, improving combustion efficiency in the lower rev range without sacrificing top-end power.
Torque characteristics are also said to feel more refined, improving engine reliability and making life easier for the rider.
The updated motor retains core features like the reverse-head layout, 39mm titanium intake valves, forged aluminium piston, plain bearing at the big end, and dry sump lubrication.
New Muffler helps lifting on/off bike stands
The exhaust system is quieter for 2026, thanks to a centrally located resonator and revised tuning. The airbox gets a resonator and ducting to cut intake noise—one of the signature traits of Yamaha 4Ts with their front-mounted airbox.
A practical tweak also lowers the muffler’s attachment angle, making it easier to grab the rear fender and lift the bike onto a stand.
New Hydraulic Clutch
A new hydraulic clutch keeps the biting point consistent under load and while riding. No more mid-ride adjustments, Yamaha says, with a smoother, lighter lever feel and more controlled feel in use.
New Chassis – “Better Stability in Ruts and Braking Bumps”
The YZ450F's new frame improves rider comfort and front-end feel. Yamaha has revised the inner structure and downtube thickness, and introduced bilateral, asymmetric engine mounts to fine-tune torsional behaviour.
This reduces rigidity in response to upward forces—without compromising lateral or longitudinal stiffness. The result is better balance, improved bump absorption, and a more composed front end. Expect these changes to filter into future WR models.
Updated KYB Suspension
The updated frame comes with revised suspension settings to match. Yamaha and KYB collaborated on a new rear shock that offers a smoother transition through the damping range.
- The base valve piston grows from 24mm to 28mm
- Separate oil circuits improve low-speed damping
- The main piston now features six ports (up from four) for better high-speed performance
- A new hand-adjustable compression damping dial makes life easier
New Seat and Smartphone ECU Locking
A new anti-slip seat surface with a honeycomb texture keeps the rider planted under acceleration but still allows easy forward movement.
For added security, Yamaha introduces an ECU lock function on all 4T models. The rider can disable starting via the Power Tuner App—useful in a world where off-road bikes often don’t have a key.
The app still lets you fine-tune power delivery, traction and launch control, and now includes a lap timer. Riders can also toggle engine maps on the fly using the handlebar switch.
70th Anniversary Editions: A Nod to the YZM400F
All models get updated graphics, but Yamaha’s 70th Anniversary Editions really stand out. Featuring red-and-white liveries inspired by the YZM400F—the brand’s first four-stroke to win at the highest level—they’re a nod to decades of racing success.
2026 YZ125 Refined
Yamaha has literally breathed new life into the YZ125 with a revised intake system, updated ignition timing, and carburettor tweaks for smoother, more linear power delivery and improved throttle response.
- New needle jet improves fuel delivery across the rev range
- Updated main, pilot and power jets refine throttle feel from idle to top end
- Bigger, reshaped intake improves airflow and consistency
- Revised ignition timing supports smoother combustion across throttle inputs
The changes aim to make the YZ125 more predictable and user-friendly, especially on corner exit.
No Changes for Enduro Models
The YZ250 and YZ250F receive updated colours and anniversary options. The WR, FX/X cross-country bikes, YZ65, YZ85, and PW50 only get new graphics this time around although the 4T models do get that ECU locking update via the App however.
Don’t forget Yamaha’s versatile trail bikes the TT-R230, TT-R125LE, TT-R110E and TT-R50E which continue unchanged into 2026.
