Athena Yamaha-Minarelli horizontal engine race kit
This new race kit for Yamaha-Minarelli horizontal engines consists of a 70 cc cylinder kit and accessories that, installed together, will deliver a race-ready performance on the engines of the iconic Aprilia Rally, Malaguti F10, F12 and F15 and Yamaha Jog models.
Produced by Alonte (VI), Italy based Athena, this additional race kit follows on from the success of its Yamaha-Minarelli vertical engine race kit. Marking its 50th anniversary this year, Athena has been a high-performance motorcycle, scooter and moped spare parts industry leader.
"Athena's R&D team has brought the innovative, patent-pending technical solutions to the design of the kit and its components - consisting of the cylinder kit and coordinating accessories that, together, will reach performance levels never achieved before".
This 47.6 mm big bore cylinder kit is described as the most powerful of its kind. "The cylinder ports are revolutionised by a new fixing system to the crankcases (patent pending) with special dedicated bolts, replacing the normal studs. The exhaust ports are thus redesigned for an increase in the engine performance in terms of torque and power.
"The 1.5 mm protrusion of the cylinder head profile allows a perfect centering of the cylinder and a further improved sealing capacity. Finally, the Athena racing crankshaft, available with 10 mm and 12 mm piston pins, is forged in steel and has lightened counterweights with aluminium inserts for improved balance at any speed".
Developed in collaboration with Selettra, the new variable advance ignition kit has a control unit with high calculation capacity, and it is perfect for the management of speed acceleration, with two selectable race mappings.
"The racing exhaust kit has been designed to make the most of the air-cooled horizontal Minarelli engine. The exhaust system is manufactured with precise craftsmanship and treated to handle the smallest particulars".
The kit is complete with the components designed for the intake unit: three air filters of different shapes, race-ready carburetors (one 24 mm with a Powerjet system and one 28 mm) and a big valve kit for engine supercharging.
