Features
Smooth and easy-to-use power
One of the most advanced in its class, the punchy 65cc liquid-cooled engine features race-developed technology such as the crankcase reed valve induction system for instant throttle response and the YPVS (Yamaha Power Valve System) for smooth torque and power characteristics, making the YZ65 an ideal bike for young racers.
Light and stable handling
The YZ65 is equipped with a semi-double cradle steel frame that features an aluminium subframe, giving light and stable handling and easy agility. Together with the 36mm KYB upside-down front forks, an aluminium swing arm and link-less Monocross rear suspension, the chassis provides outstanding stability and consistent lap times.
Effortless 6-speed transmission
Carefully chosen gear ratios for the 6-speed transmission have been specially developed to enable the rider to achieve lower lap times by fully utilising the performance of the 65cc engine. Yamaha engineers have also designed the clutch plates and springs to give a light and easy clutch lever character.
Confident cornering
The 36mm KYB upside down front forks underline the fact that the YZ65 shares the same pure racing DNA that goes into our other YZ models. With their excellent rigidity, they give a planted front-end feel for confident cornering – and their long-travel tubes are built to soak up the bumpiest surfaces.
Smooth and stable riding
The Monocross rear suspension is designed to deliver a smooth and stable ride, and not to bottom out even on the harshest circuits. The lightweight aluminium swingarm enhances the suspension's character and gives extra comfort and features a link-less design that reduces routine maintenance requirements.
Adjust your YZ65 as you grow
Young riders grow quickly, and therefore the YZ65 has been equipped with an aluminium crown featuring four different handlebar positions, giving a total of 27mm forward/backward options to suit your size and riding style. Like our bigger YZ models, tapered handlebars come as standard, and give an ideal balance of shock-absorbing flex and immense strength.
Total control in your hands
The right body position is vital if you want to maintain full control of your YZ65 and win races, and the seat with new skin is designed to enable you to shift your weight forwards and backwards to suit changing conditions. The body panels are also designed to give free movement, allowing you to move easily around the bike for a race-winning ride!
Pure YZ race-bred DNA
The new PVC handlebar pad is the same one used on the bigger YZ models. It offers better water resistance and adds to the light, agile YZ look and feel. Further emphasising the family connection are the YZ-style rims and updated colours and graphics. This is the ultimate entry-level YZ racer – and if you're serious about winning, you need to be racing with the YZ65.
Easy maintenance and reliability
To match its performance and handling, the YZ65 also delivers reliability and ease of maintenance. For 2027 the YZ65 front wheel bearings have been upgraded to an oil seal type. This increases water resistance as well as improving maintenance ease and reliability.
