Exhaust Valve MALOSSI V4 Head

M3813273 for Leader/Quasar
125-300cc 4-stroke, LC
2 pcs

only for the MALOSSI V4 cylinder head

The perfect addition to all PIAGGIO liquid cooled Leader and Quasar motor set ups! As the market leaders in the manufacture of performance parts for four-stroke Maxi-scooters, MALOSSI present the 'V4 Cylinder head'. This aluminium four valve cylinder head is manufactured using the highest quality materials. The factory-assembled valve-train components undergo an extensive tempering process for improved stability. The enlarged and gas-flowed inlet and outlet valve channels are the main contributors to the increased performance, while the valve seatings are treated with a high-tech alloy to ensure minimal operational friction. In combination with a performance orientated cylinder, MALOSSI promise an increase in power output of up to 20%! This cylinder head conversion kit has been conceived to be fully compatible with both the Leader and Quasar PIAGGIO motors. Full instructions are included with these kits outlining in detail the modifications necessary for their inclusion in the set up of your motor.

 

MALOSSI cylinder head / four valves / four stroke

Performance cylinder head made using cast aluminium alloy, heat-tempered, sand-blasted, MALOSSI promise a power increase of between 15-20% (according to peripheral set up), hardened inlet and outlet channels, optimised outlet channel angle, enlarged inlet and outlet valves (25mm and 22,2mm diameter respectively). Hardened valve seatings, treated with a Cobalt-molybdenum-steel alloy and coated with copper for reduced friction, All valves are produced using Nimonic 80 (a nickel, chrome, titanium and aluminium alloy) and gas-flowed, valve springs are made with an oil-tempered Si-Cr-Steel alloy, this cylinder head is factory assembled and is delivered ready-to-mount.

 

SIP–TIP : This cylinder head can only be used on the liquid-cooled 125-180cc Leader motors in combination with the 209cc performance cylinder (#M3111473), also produced by MALOSSI. The MALOSSI piston (#M3414086) with enlarged valve recesses is also required, but already included with the previously mentioned 209cc cylinder kit. In combination with the 250-300cc Quasar motors the valve recesses on the crown of the original piston will require modification. Detailed instructions concerning these modifications are included in the delivery.
