Spare parts for the powerful 2-stroke heart of your moped
Engine and gearbox parts are exposed to mechanical and thermal stress every time you ride, which wears away at their substance over time. Every ignition process in the cylinder generates high pressure, which is transmitted via the piston, connecting rod, crankshaft and gearbox to the rear wheel and ultimately ensures that you move forwards on your motorbike. Engine and gearbox parts wear out sooner or later due to this high material stress. Unfortunately, this also applies to your Tomos moped. However, it is often only a minor defect that can be repaired quickly with little effort. Whether it's broken teeth in the gearbox, a defective clutch, worn needle bearings and seals or a defective kickstarter. With the professional tools as well as the necessary reproduction or original parts, you can quickly repair most defects yourself.
