The Motion Pro Vortex SE Throttle Assembly represents a completely redesigned iteration of the Vortex line, featuring a lighter, ultra-compact profile that maximizes available handlebar space. Constructed from die cast aluminum with a billet aluminum cover and finished in smooth painted black, the unit incorporates a POM pulley paired with a brass bearing to ensure a smooth operating feel and extended wear resistance. This assembly is compatible with 7/8" (22 mm) bars and integrates with Motion Pro DirtControl™ V2 and ODI V2 Lock-On grips using cam ‘C’, while the included Motion Pro Titan Throttle Tube™ provides enhanced durability for the throttle cable housing.
Engineered for precise control, the Vortex SE delivers a fast twist rate that opens the throttle at 0.526 mm of cable pull per degree of rotation. This design allows the carburetor to reach full throttle on most 2-stroke bikes within just 70 degrees of rotation, with a maximum twist of 95 degrees pulling 50 mm of cable. The assembly replaces the OEM throttle on many Japanese 2-stroke MX bikes, including the KX125/250 (92-05), RM125/250 (95-05), YZ125 & 250 (96-10), and WR250Z (97) with stock cables. For Honda CR125 (93-03), CR250 (90-04), and CR500 (90-01) applications, the unit is designed to be used with Motion Pro Cable P/N 70-1713, while special application cables are available for other models.
