 Ariel 1932   “ MF  32”   350 cc     OHV       frame#  1248  engine#    B 8647

This machine has the cylinder inclined forward at 45 degrees to the vertical. 
The sloping engine was a popular design feature around 1930, with the famous BSA “ sloper” as leading model. 
The craze lasted about half a dozen years: by the mid thirties there were hardly any sloping models left; Panthers being a notable exception of course. The 250 cc OHV Colt model of 1930 had been a good seller, but there  was some demand for a similar machine with slightly better overall performance. 
So  in March 1931 the factory introduced a 346 cc OHV version of the Colt, with 72 mm bore and 85 mm stroke. 
The model has a two port head and was priced at a modest £ 42. Magdyno lighting was an optional extra. 
Gearbox is 3 speed Burman, dry sump  lubrication by twin plunger pump. 
Primary chain is enclosed in a cast-aluminium oil bath. Some of the new features for 1932 were a redesigned inlet port ( giving improved performance),  bigger diameter and wider brakes and a black enamelled pressed-steel cover for the gearbox. 
This light and agile Ariel has pleasing lines and is a well-restored motorcycle.
