MPL Molnar Manx 95 Bore Specification

Developed in conjunction with Fred Walmsley, the 95 bore Molnar Manx has been the machine to beat for many seasons. Winning 6 out of 7 International Classic British Grand Prix support races, the 2000, 2002 and 2006 Classic Senior Manx Grand Prix, the InCA 2002 European Championship, FIM 2003 Classic World Series and numerous other International events. The late, sadly missed double world champion Barry Sheene chose the FWD Molnar Manx 95 bore for his personal machine to campaign in Classic events, the best endorsement you can get. More recently, winning the CRMC 500cc GP Championship in 2015, 2017 and 2018.

All parts are machined from original castings to ensure authentic appearance.

95mm bore x 70.38 stroke = 499cc

Pressed up crank assembly, with integral mainshafts, made from EN36 forgings hardened and ground all over. 40mm parallel pin and INA needle roller big end bearing with custom designed lightweight Carrillo con rod. We believe that these proven crankshafts give the optimum combination of rigidity and flexure for the Manx, but if the customer insists, we can supply our engines with a one piece EN40 billet crank and carrillo con rod at extra cost.

Special forged 2 ring piston, running in a ceramic bore in a lightweight barrel casting. Maximum safe RPM = 9,000. Optional billet barrel.

Cambox and cylinder head valve angle reduced to 60ø inclusive with valves re-positioned to suit. Inlet port and combustion chamber totally re-designed. Twin 10mm spark plugs.

Almost every part has been worked on to reduce the weight of the engine to 77 pounds (35 kg) excluding magneto and carb.
