Yamaha knows that champions win on the highest quality competition parts and Genuine Yamaha Technology Racing (GYTR®) combines top-level knowledge from the Yamaha Racing R&D department, with decades of Grand Prix experience, to give motocross riders the best possible performance in all race conditions without compromising engine durability.
For new and freshly overhauled YZ125 twostroke production engines, the new GYTR® YZ125 High Performance Kit represents the ultimate and powerful racing edge.
The new 2016 kit includes a GYTR® cylinder head with detachable combustion chamber inserts, a GYTR® ported cylinder with pre-installed oil seals on the exhaust valve shaft for improved port airflow and a GYTR® YZ125 piston, made from unique materials for a profile that is completely different to the standard production piston.
Also new in the 2016 YZ125 High Performance kit is a carbon fibre VForce reed valve air intake system for better throttle response, a GYTR® exhaust pipe for well-balanced performance in both the middle and high RPM ranges and a titanium GYTR® silencer maximized for power and durability.
Finally the kit includes a GYTR® CDI with the latest 2016 map, a magneto rotor unit with higher inertia mass for more torque and a carburettor needle/jet set for adjustments in changing weather, elevation and track conditions.
Yamaha rider Maxime Renaux won the 2015 MX Junior Championship on a YZ125 using the high performance kit parts and now it’s your turn to follow Maxime into success on the track!
