ZF Sprockets Rear Sprocket 45T – Fantic CAB 700

The ZF Rear Sprocket 45T is a premium drivetrain upgrade engineered for motorcycles using a 520-pitch chain (verify pitch with your CAB 700). It features a 45-tooth rear sprocket count, which leads to a slightly lower gearing ratio — giving stronger acceleration and more accessible torque at lower RPMs while only marginally affecting top speed and highway cruise.

Manufactured using ZF’s “Dual” construction technology, this sprocket combines an aluminium alloy outer ring with a hardened steel inner gear ring. The result: a component with high durability, reduced rotating mass, and improved responsiveness compared with standard steel sprockets. The surface is anodised or colour-coated for enhanced corrosion resistance and lasting good looks.

Installation is straightforward provided bolt spacing and chain pitch match: remove the wheel and old sprocket, fit the new 45T ZF sprocket with correct mounting bolts, torque to specification, adjust chain tension and alignment. The upgrade is particularly beneficial for riders who do mixed riding (urban + light trail/off-road) or want slightly quicker throttle response without resorting to overly aggressive gearing changes.

Key Features:

45-tooth (45T) rear sprocket for use with 520-pitch chain systems.

Dual-material (“Dual”) construction: aluminium + steel for strength and light weight.

Anodised/colour-coated finish for corrosion resistance and aesthetic appeal.

Direct-replacement style for compatibility (verify bolt pattern, chain pitch and mounting hub).

Optimised for enhanced low-end torque and improved throttle feel while maintaining overall gearing balance.

Durable and suitable for both street and light off-road use.
