Top to bottom, this PR2 MOD KTM 105SX is getting the attention it deserves before heading back to the gate. This rebuild included both top and bottom end service to ensure maximum performance, reliability, and durability when it matters most.
Featuring a Wossner Pistons N.A Performance connecting rod kit and dual ring piston, this engine is built to handle countless laps and race weekends ahead. When it comes to cylinder work, there’s only one choice for us. As always, we trust PowerSeal USA for cylinder plating and finishing. Their quality, consistency, and attention to detail are second to none.
It Just Works.
