Aprilia RS4 125 4T Parts & Spares – Only Genuine Parts Sold – Guaranteed.Buy original, new parts for a RS4 125 4T motorcycle from Europe’s Number 1 spare parts provider - MSP.
The four-stroke replacement for the much loved, screaming, 30bhp+ two-stroke RS125 was forced upon Aprilia by ever-tightening European emissions regulations and, with just 15bhp, was never likely to match its predecessor’s performance or thrills. Even so, with its glorious, GP styling and chassis, the Aprilia RS4 125 4T is still the most desirable sports 125 of all, almost certainly a better learner prospect and yet still delivers an authentic, credible sports bike experience in terms of handling and style.
