Description

When your 2-stroke 250cc engine shows signs of wear—loss of compression, sluggish throttle response, or visible carbon buildup—a complete rebuild is the most cost-effective path to restoring full performance. The Wiseco PWR179-100 kit eliminates the guesswork of sourcing individual components by bundling everything you need for a proper top and bottom-end overhaul. Whether you're preparing for race season or bringing a tired machine back to life, this kit ensures reliability and consistent power delivery without compromises.

Built for serious riders who demand precision engineering, this Wiseco rebuild kit pairs Pro-Lite® piston technology with OEM-quality bearings and seals—the combination that separates a proper rebuild from a temporary fix. You get the exact specifications KTM designed the 250 SX for, meaning no guesswork on fitment or compression ratios.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
