Bland single with poor economy compared to the SP400, which shares a similar motor. Boring looks hide a certain toughness, some engines have done 60k; top end first to give hassle, especially the rockers. 6V electrics rather naff and they rot with age, as does most of the chassis. Chronic swinging arm bearing demise, best to make up some phosphor-bronze bushes. Vibes around 4k normal. Still some well cared for examples on offer, not many rats left.
