About Lem

Company History
LEM specialized in small off-road bikes that introduced generations to dirt riding—50–125 cc machines sized for kids and teens, with ergonomics and power delivery tuned for learning. Italian suppliers provided quality forks, wheels, and brakes, while simple two-stroke singles kept maintenance approachable for parents and club mechanics. The brand’s presence at regional events—training days, junior enduro and MX—meant rapid feedback loops on durability and setup. As emissions rules tightened and four-strokes rose, LEM adapted with cleaner engines and updated safety equipment, but the core remained: light, tough frames and components that survive tumbles. Historically, LEM embodies Italy’s commitment to youth development in motorsport. By delivering honest, fixable hardware that rewards good habits, the company helped seed a talent pipeline and gave countless families a reliable first step into the lifelong ritual of the paddock.
