J.A.P. JA Prestwich 175cc SV Sidevalve short vintage motorcycle engine 1920.Turns smooth – SOLD


J.A.P. JA Prestwich 175cc SV Sidevalve short vintage motorcycle engine.

I believe it dates to 1920. See the image of the engine number. The number ends with V/V. One of the V’s means that it’s a 175cc JAP. The other V might mean that it has a “reduced centre connecting rod”.

It turns over with ease and comes as you see it, with the crank and connecting rod, together with the inner timing cover and outer cover. The engine case halves have matching numbers.

The inner timing cover appears to have been re-plated with nickel. The outer cover is a bit rough. While it’s definitely a JAP outer cover, it looks a bit long for this engine.

From the limited information available, the 175cc  JAP side valve engine was supplied to a few vintage motorcycle manufacturers including Francis Barnet in 1926. I think Excelsior also used 175cc JAP motors.

Overall, it’s in very good condition. The only thing worth mentioning is a small split along one of the lower engine mounts.I have shown it on the images.

Fun fact: E C Fernihough, who held and still holds, the outright speed record for a motorcycle at Brooklands on an Excelsior J.A.P. 175 c.c. motorcycle, at the Brooklands race track.

If you are on the hunt for a J.A.P. (JA Prestwich) 175cc SV Side valve short engine, then this is a nice one.
