In some forms of racing, two-strokes still rule. One is western off-road races like the National Grand Prix Championship. There, two-strokes go head to head with four-stokes of the same displacement. For the 2019 season, Troy Vanscourt built a KTM 250SX for the 250 expert class and Pro 2. He chose the SX because it has a more aggressive power delivery than the XC, and because it’s lighter–no electric start. Here’s how the project came together.

Scott, Darren and the crew at ZLT designed a custom set of graphics for our off-road project that gave it some bling factor.
  • Precision Concepts re-valved and re-sprung the shock for our off-road application and reworked the WP air fork to match.
  • Supersprox Stealth rear sprockets feature an aluminum core for weight reduction and steel drive teeth for increased wear life.
  • The IMS Core footpegs are available in three different sizes—MX, Enduro and Rally—with standard or sharp teeth.
  • Blais Racing ported and polished the cylinder for some additional performance without compromising durability.
  • The GPR Version 4 Pro Stabilizer kit comes complete with a top triple clamp, bar mounts, a frame mount and a Version 4 under-the-bar stabilizer. 
  • The IMS oversized tank holds around 3 gallons and is available in multiple color choices with a quick-dump or screw-top option.
  • Seal Savers are made of neoprene and designed to fit over your fork seals to keep out debris and prevent damage that might cause the seals to leak oil or air.
  • The Warp 9 wheelset provides some much-needed strength to handle grueling off-road-style events.
  • Nitro Mousse foam inserts have a high concentration of nitrogen in a micro-matrix of proprietary elastomers, giving them a tube feel without the possibility of flats.


Pro Circuit’s original works pipe constructed of AKDQ-stamped carbon steel was teamed with the very popular 304 Factory Sound silencer. We did this seeking performance improvements, but with its stainless steel aluminum construction, durability is increased as well.
The Kenda Millville II tires feature a directional design for use in soft to intermediate terrain with a brand-new compound that is designed to provide improved traction without compromising long-term durability.
The new carbon, Kevlar and biaxial fiber-glass bash plates from P3 Carbon combine a smooth-flowing design with seamless construction. Every design provides your engine and frame with the most protection possible and is model-specific.
Through the use of proprietary, thin-friction technology, the Rekluse TorqDrive system is able to fit more plates into the clutch pack, providing more torque transfer, a precise lever feel and durability with billet components. The system is also adjustable using different spring combinations.
