The Werks Team Line B5-Pro II is a revised version of the renowned B5 Pro. Werks engineers went back to the drawing board, and made the B5 Pro even better! The B5-Pro II produces aggressive stump pulling bottom end power, with strong mid and top end that makes it a great truggy engine. Additionally, the B5 Pro II is well suited for buggy applications when you want aggressive power and insane bottom end.

Engine includes a Werks TLP5BT #5 Turbo Glow Plug. The glow plugs recommended for this engine are the Werks Racing TLP5BT #5 and TLP6BT #6. Pipe recommendation is Werks Racing 2013 (WRX6658C) for Truggy use and Werks Racing 2058 (WRX6659C) for Buggy use.

B5-Pro II features:

  • Revised port timing for improved performance.
  • “Swiss” ceramic rear bearing for improved reliability and reduced friction.
  • Double shielded front bearing for improved reliability.
  • Lightened and epoxy ramped crankshaft allows the engine to spool up faster for improved acceleration and improved fuel economy.
  • Black anodized crankcase for improved heat dissipation.
  • Billet rear back plate to reduce weight and create a more rigid case assembly.
  • Improved carburetor heat shield to improve carburetor consistency and reduce possibility of heat saturation.
  • Revised carburetor design for easier tuning and improved stability.
  • Modified crankcase and new super low CG wrap around head design for improved heat dissipation and reduces overall CG of vehicle for improved handling.
  • O-ring sealed head button for improved sealing and reduces the likely hood of dirt entering engine during routine maintenance.
