CYLINDER WORKS cylinder kit for SUZUKI RM-Z 250 and KAWASAKI KX 250 F from 2004 to 2006

CYLINDER WORKS offers this cylinder kit for SUZUKI RM-Z 250 and KAWASAKI KX 250 F from 2004 to 2006. The cylinder kit groups a cylinder and the parts to fit it (piston, rings, gaskets depending on the kit: see contents). “Big bore” kits increase the bore and therefore the displacement: the engine gains torque and power.

Why buy a cylinder kit?

The benefits:

• A cylinder and its matched piston: perfect fitting clearance.
• One order to rebuild the top end.
• Big bore versions give more torque and power (check the rules if you race).

Why choose CYLINDER WORKS?

Cylinder Works supplies brand-new, not remanufactured, cylinders with a nickel-silicon-carbide coating; its kits come with a matched forged Vertex piston.

When should you replace the cylinder?

Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.

Recommended hours for a top-end rebuild (manufacturer recommendation for the Suzuki RM-Z 250 / 450):

• Racing: every 12 h (about 6 races).
• Leisure: no Suzuki figure; Cross-Mania guideline: compression check at around 24 h.

Specifications and fitting tips

• Displacement: 250 cm³
• Engine: 4-stroke
• New replacement cylinder head
• Includes cam caps and cap bolts

Cross-Mania tip: Check the diameter of the supplied or required piston and replace the top-end gaskets. A big bore may require carburation or fuel-injection adjustment.
