YX 160 engine first choice 2026

Stock engine with the best “out of the box” setup! Unlike many of the imported versions found on the market, this is the one that allows you to have an engine ready to hit the track as it comes out of the box. The gear ratio is the most versatile in existence (13-34. 17-29. 17-23. 20-21) and is the same as the zs155 GPX engine, as is the ignition and electrical system. It also comes with a quality 90-degree manifold with sleeve coupling that fits perfectly on modern perimeter frames and smoothly accommodates all 26- and 28-mm carburetors on the market. Titanium valve plates are also already installed, ensuring performance and reliability even at high rpm. The engine is equipped with a kick starter shaft.
