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:
 |
100% greater coolant capacity over OEM cylinders. | |
|
|
Full water jacket exhaust port tunnel for fade-free power. | |
|
|
O-ring head gaskets for optimum heat transfer and easy maintenance. | |
|
|
Custom forged piston kit. | |
|
|
Removable iron liner makes Pro-X cylinders infinitely rebuildable. | |
|
|
Modern 10-window CT porting layout. CT builds each cylinder order according to your requirements. You may specify your preferred power characteristics. |

| GA-C7390 |
TRX250R Cometic Top-end Gasket Set with CR Style
Head Gasket - 68mm (stock cylinder) This is a great little hop up trick for a stock 250R. This head gasket is paper thin at only .011 thick. It actually would raise the compression a bit too much for pump gas, so we supply two base gaskets raising the cylinder up slightly. This acts like mild porting. It sets the compression for pump gas and picks up about 4 HP with a wider power curve and more bottom-end power. |

| AX-DB-20-1151 |

$347.40 |
 |
| AX-DB-20-1151SP |
'86-'89 TRX250R/ATC250R Dura Blue Eliminator 2+2 Extended Axle The Eliminator axle used for all forms of racing and high performance applications. Many of the models come with the patented Posi•Lock system which removes threaded sections from the flexing area of the shaft (a source of crack generation). |
$433.80 |
|
| AX-DB-20-1151EX |
'86-'89 TRX250R/ATC250R Dura Blue X-33 Pin Drive Axle with Cast Hubs The X-33 axle uses the same superior material and heat treating as the Eliminator. The unique difference is in the design of the wheel hub mounting area. Standard design ATV axles neck down to about 1" in diameter. A splined wheel hub slides onto the axle shaft and is retained with a hex nut. As all ATVer's know, hubs loosen frequently. The X-33 changes all that. The wheel hub is clamped solid and driven by a pin on a 1-3/8" diameter shaft. This axle is rifled to reduce weight near the rotational axis of the ATV. The X-33 allows for 16 different wheel offset alternatives. |
