The Jappic, first entered at Brooklands on the Easter Monday meeting of 1925, was a tiny two seater cyclecar that had a 344cc JAP motorcycle engine. The car was designed by H.M.Walters and built by the coachbuilders Jarvis of Wimbledon. The frame was made from the wood ash with 3/32 inch steel flitch plates and tubular cross-members. It had expanding rear brakes on the rear, but no front brakes. The wheels where shod with 650x65 motorcycle tyres, which were attached by a chain-driven axle to a two-port overhead valve 74x80mm single-cylinder JAP engine via a three-speed gearbox.
