The LSE was the competition-derived 620 LC4 with a shorter-travel WP suspension package and a 139 kg dry weight, lighter than the Adventure. Its 609 cc single was tuned for enduro and off-road racing, and it was sold as a street-legal machine. The page's review describes it as brutally powerful, with a demanding ride for road use.
