Easy to navigate website & reasonable postage considering delivery from the Netherlands to UK. Found what I needed for my 22 year old GSXR. Would definitely use MSP again

Motorcycle Spare Parts only sell genuine spare parts made by each manufacturer. The Main Wiring Harness part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
Main wiring harness 642823 (replaces AP8127559) is the central nervous system for your bike’s electrical parts like ignition, lights, sensors and indicators. It’s used on Sport City 125‑250 and Rambla 125‑250 models (2004‑2012) from Piaggio/Aprilia/other related brands. Genuine harnesses reduce the chance of shorts, faulty signal paths, or intermittent issues caused by worn or inferior wiring.
This genuine harness uses factory‑grade insulation and connector finishes to resist vibration, moisture, and heat. If you’ve had frayed wires, flickering lights, or intermittent sensor warnings, this is one of the first parts to check.
