EVP's XR Series Billet Cradle provides additional stability to the bottom end to run BIG boost. Machined from a solid block of 7075 T6 aluminum for maximum structural support and reinforced in critical areas. Our own in-house engines have made 700+ horsepower with the XR Cradle. In addition to the added strength, the XR Billet Cradle gives you the ability to stroke your X3 without machining out the lower case!
The Maverick 900cc Rotax engine is limited in ways to increase the displacement of the engine. While the engine can be over bored slightly, the largest gain in displacement is by combining the XR Series Billet Engine Cradle with the BC/EVP Stroker Crankshaft, Piston and Connecting Rod Set. The 3.5mm increase in stroke and a 2mm overbore will get you to 999cc of displacement. With a 1mm overbore, 975cc.
