Not positive on pricing but they are somewhere in the $2000 to $3000 dollar range. That will seem like a lot to some but it really is not when you consider your getting a purpose built race bike with all the goodies.
If you were to built a 150cc Maddog to race you could have $3000 tied up in the price of the bike alone then you need a cam, carb, pipe, tires, maybe even wheels plus your labor so these bike really are a good value.
Hope Santa bring me one. LOL!
Merry Christmas.....O.J.
