Engines only, not whole bike. I found a dyno chart for the X, but not the R. Also need prices for STOCK engines either the X and/or R. External dimensions too. Any comparable **250cc 4 STROKE** engine with specific technical data welcome. TIA ---

![http://www.motorcycle-usa.com/photos/CRF250XDyno.jpg](http://www.motorcycle-usa.com/photos/CRF250XDyno.jpg) and an awsome Excel generated plot for the R… ![http://www.rickramsey.net/CRF250Xlg/HpTorque.jpg](http://www.rickramsey.net/CRF250Xlg/HpTorque.jpg) I found a price of $1,999.99 new for a CRF250R, but of course my design doesn’t need a tranny :smash2: So, I doubt any external dimensions are going to help me. ---

2k is a good price for new, they usually start around $1500 used on ebay. I hear the YZ250F puts around 38hp incase your wondering. What are you planing on doing with the motor? ---

I’m just throwing around ideas, but the engine will only be used on paper. Formula SAE has a new competion Formula Hybrid. Any stock 250cc 4 stroke engine can be used as either charging (series), propulsion (parallel) or both. Basically re-use an old chasis that normally uses a 600cc engine, pull it out, throw in an electric motor, more batteries than praticle, and a 250cc engine. I doubt it will ever get built, but I just wanted to learn more about Electric Vehicles and it would be an interesting design. ---
