Top Performances Cylinder Kit 86cc cast iron + Crankshaft stroke=44mm Derbi Euro3

Top Performances is one of the go-to brands for top quality but still affordable tuning products. Derbi owners can now get a complete tuning kit: Top Performances Cylinder Kit 86cc cast iron + Crankshaft stroke=44mm Derbi Euro3. The kit includes:

• cast iron cylinder, 50mm bore / 44mm stroke
• 1-ring piston (1mm)
• modular cylinder head
• gaskets
• crankshaft, 44mm stroke

Though you can buy and use both components of the kit on their own, they are designed to be used together to achieve optimum performance. The cylinder's kick-ass 86cc displacement is perfectly supported by the reinforced crankshaft. Output and torque are impressive, engine performance is great from start to finish but shines at mid to very high rpms. To unleash the full power of this kit, we recommend adding some other tuning components: a racing exhaust, a larger carburetor (24mm) and a reinforced clutch.

With a well-done set-up, you can easily reach 19 hp - not bad! Even better - the kit is not over the top expensive so it might be a good starter kit for people who want to get into racing.

Specs:

• port timings: 192° / 132°
• recommended squish: 0.9 - 1.1mm

Note: you have to make room for this kit by opening up the crankcase a bit; a manual is included. The cylinder is not road-legal.
