We know when you love something changing it can be upsetting but, we couldn't resist. We decided to go ahead and make it even better! Werks Racing is pleased to announce the release of our new B5-Pro and B6-Pro engines. Improving upon what has arguably become two of the bestselling engines in the USA is never easy but, Werks Racing designers were up to the challenge and they really stepped up to the plate! We kept the basic performance characteristics of the aggressive bottom and strong mid/top of the B5 and the super smooth, linear powerband of the B6 in place. And then we kicked it up a couple of notches with our new Pro versions.
We started by putting in ceramic rear bearings and a lightened and epoxy filled crankshaft for the Pro versions. These engines now, spool up faster providing increased acceleration AND fuel economy! We went with black anodized crankcases not only because they look sharp but, also because they provide for increased heat dissipation. Performance and durability! The rear back plate is CNC machined from high quality aluminum billet, reducing the weight and increasing the rigidity of the case assembly. A new heat insulation sleeve improves, carburetor performance and minimizes the likelihood of heat saturation. Finally, everything is topped off with a new, large diameter, cooling head which, not only improves heat dissipation but, lowers the overall CG of the engine. We accomplished this by reducing the head weight 5% over the standard B5 & B6 heads and an up 'til now an unimaginable 10% over our 2010 design!

The tuned pipes recommended for this engine are the Werks 2013 for strong top and bottom power delivery, 2058 for top end power, or 2057 for smooth power with improved mileage.

NOTE: This engine includes a Werks TLP5BT #5 Turbo Glow Plug. The glow plugs recommended for this engine are the Werks Racing WRXTLP5BT #5 Hot, and WRXTLP6BT #6 Medium. In most cases the WRXTLP6BTwill be the best choice.
