📦 Full Description
Meet the Zeda 100 Max (LD100) – the all-new 2-piece cylinder engine that takes everything great about the original YD100 and dials it up. With a larger 50mm bore and separated head/cylinder setup, this design gives you better heat dissipation, more durability, and endless tuning potential.
You’ll notice faster starts, steadier power delivery, and a quieter, smoother ride. The silver pearl anti-corrosion coating protects the internals, while upgraded bearings and crankcase thickness bring long-lasting reliability even under heavy loads.
The large 40mm intake stud spacing and round 21mm exhaust port give you flexibility with performance upgrades like reed valves and tuned pipes. All in all, this is one of the most complete, powerful kits you can bolt onto your ride.
🔥 Get yours now while supply lasts—this isn’t just an engine upgrade, it’s a transformation.
