BUGGY ENGINE GUARANTEED FIT FOR YOUR BUGGY

Our BDX buggy engine is guaranteed to fit your buggy. Call our technicians at 434-447-4870 and we 100% guarantee that the engine that we ship will fit your buggy.  

The Chinese-built GY6 150cc buggies built from 2000 to around 2011 all use the same GY6 engine.  However, you will not find this engine anywhere else in the world that is a direct bolt in for your buggy.  We modified engines in our facility in VA to fit your specific buggy.  Give us a call today and talk to Doug..

Sure you can purchase a scooter engine and modify it to fit your buggy. You could do the same thing with a golf cart or motorcycle engine.  Why hassle with all of that trouble when you are guaranteed to get the exact right engine for your buggy, from BDX, with no modifications.  And what if you order an engine that will not fit your buggy.  

Our technicians work on buggies everyday and they know exactly what engines go into what buggies.  Call us 434-447-4870.

Our standard GY6 engine  works on the Yerf Dog Spiderbox 3206 and 4209, the yellow Tomberlin Crossfire 150, Blade, Kinroad, Twister Hammerhead, Carter Talon, Baja Dune, SUNL, ROKETA and many more. If you have an external reverse you simply remove your gear box from your old engine drive shaft and install it onto your new engine drive shaft. 

Does Your Buggy Have an Internal Reverse?
If you have a newer buggy such as a TaoTao, Explorer, Scrambler, Raptor, Falcon, Kandi Spider, Tomberlin Crossfire 150R, Baja Reaction, American Sports, Trailmaster or UTV such Yerf Dog Rover CUV or Bull Dog Pup you will need one of our internal reverse engines for buggies.  We guarantee fit on those as well.

The large 27mm/24mm valves allow the engine to breathe better at high RPM, allowing for higher top speeds. This is a very noticeable improvement if your original engine came with the smaller 24/23 valves.

^{8-pole charging upgrade}Also includes STAGE 1 Electrical Upgrade
