Arguably one of the coolest 250R's ever built.

 

CT/Pro-X cylinders are the leading power producing upgrade currently available for Honda 250R engines. CT/Pro-X cylinders are available from 250cc to 410cc (stroked). Whether you are building a "drag only" ATC or an "all round fun" 4Trax, CT has a combination to suit your needs. All CT/Pro-X cylinder kits include these advanced features: 

bullet   100% greater coolant capacity over OEM cylinders.
