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 Halbhauptlager part has been manufactured by Piaggio and is brand new and dispatched in its original packaging.
The Halbhauptlager (2A0008370V), often referred to as the half main bearing, is a precision bearing component used in the transmission or drive assembly of various Aprilia, Derbi, Moto Guzzi, Vespa, Gilera, and Piaggio motorcycles. It supports and stabilizes part of the drive shaft or gearbox internals, helping to reduce play and wear under load.
When your shaft shows endplay, noise, or misalignment, replacing this bearing is crucial. Because it’s an OEM Piaggio component, the tolerances, material hardness, and bearing dimensions match the original spec. Fit it carefully with proper tooling (press or driver) and recheck clearances to restore smooth drivetrain behavior.
