Neval Motorcycle Imports, New Holland, S. Humberside (near Hull).
Based at the former RAF Elsham Wolds airfield.
Originally a Cossack dealer, they took over importation of the Minsk in the mid 1970's before becoming the sole concessionaire to import most of the Soviet-based motorcycles in 1979. They retired the motorcycle arm of their business in the mid-1990s.
August 1980 Models
1981 Model Intruder 340cc single cylinder twostroke, Hella 12v electrics, optional mag wheels. Drum brakes front and rear. Possibly a modified IZH, and appears to be a twin despite advertising literature stating that it's a single.
1990 Neval Jupiter 5 was an IZH two-stroke twin.
Their trials bikes are thought to be derived from Montesa.
