The 5.1i Enduro swaps the carburettor of the earlier 5.1 for Magneti Marelli electronic fuel injection with digital engine management. The rest of the package, a 500 cc dry-sump single in a chrome-molybdenum frame with Paioli/Kayaba suspension, carries over. It remained a lightweight, electric-start four-stroke enduro machine.
