The Namura NX-70051 Piston Kit is designed for select 250cc two-stroke motorcycles equipped with Nikasil-plated cylinders. This standard-size piston kit features an 11:1 compression ratio and is manufactured to support reliable engine performance, consistent compression, and proper piston-cylinder fitment.
