TM 250Fi GP (Electric Start) 2019

TM 250Fi GP MX 2019


The high-end specification of all TM Racing machines is well versed and for 2019 this is no exception, once again the specification list for a production machine is vast and features numerous high-quality components, many revised for the 2019 model ranges.

250Fi 4-Stroke Engine – Single Cylinder, Water Cooled, 4-Valve, Twin Cam, Fuel Injected.

Hand finished crankcases and cylinder heads, lightweight and strong die-cast clutch casing, clutch inspection, water pump and ignition covers, cast water pump rotor, billet machined crankshafts (running on roller bearings with ‘hi-tech’ crank-seal), billet connecting rods, box-bridged pistons with DLC coated gudgeon pins, hand finished cylinder heads, titanium valves matched to copper beryllium valve seats, chain driven overhead twin camshafts actuating ‘finger followers’ , twin rotor oil pump (dry sump type arrangement), high performance – long lasting clutches, ‘cush-drive’ clutch baskets, friction reduction hard coated clutch baskets, friction reduction hard coated gearbox selector fork tips, hardened gear-shaft parts, 6 speed (differing ratio) gearboxes, hydraulic clutch actuation, Battery-less ‘down-draught’ Electronic Fuel Injection, Kokusan digital variable advance ignition with twin map selection working with the fuel injection systems, gear position sensitive variable ignition timing, HGS ‘bomb’ type Exhaust systems. Electric start is standard fitment on UK MX models.

For 2019 the 4-stroke range will retain the current ‘reverse’ chassis configuration with fuel tank under the seat and the air intake above the engine. This layout has seen a huge transformation in the handling characteristics of all the 4-stroke models since it was introduced in 2015 and has been gradually improved upon year on year. Centralised mass, better outright balance and revisions to the geometry and suspension settings have allowed TM Racing to create and incredible range of 4-stroke machinery all with superb ability and agility.
For 2019 we have numerous engine changes to the ‘twin pipe’ MX engine with its unique cylinder head and camshaft arrangement.

The MX 250Fi ES-4S engine will receive a new ECU and operational system, programmed to work alongside a new air intake system, maximising the responsiveness and outright engine performance of this already incredible and only recently developed engine.
