Description
BIG BORE Ø 50

From the technology of the famous MHR Trofeo Malossi Scooter seven-port thermal units, the new BIG BORE Ø 50 thermal units, stroke 39.2/39.3 and 44, have taken shape, designed for Minarelli and Piaggio engines.
All the pilots, enthusiastic about the novelty, wanted to test them. The results were not long in coming: the increase in power and absolute reliability demonstrated, once again, the quality of the product and the professionalism of the Malossi company.

Technical features:
- Seven-port cylinder, H2O, gravity-cast in hardened aluminum alloy, cermetal coated barrel smoothed with diamond tools
- Bore 50
- Reinforced single-ring piston with domed head
- Segment Ø 50 x 0.8 in KDN5 cast iron
- Split head in hardened primary aluminum alloy with calculated and oriented cooling circuit conveyance system.

Technical note: BIG BORE thermal units have been designed to be used exclusively in combination with Malossi crankshafts.

ATTENTION: To ensure the necessary rigidity of the thermal group, the cylinder has an insertion diameter in the engine crankcase of 56.2 -0.1/-0.2 mm. It is therefore necessary to bore the crankcases with a 56.7 +0.0/0.1 mm boring bar to a depth of 21 mm.

Products reserved exclusively for competitions in places specially designed for such purposes according to the provisions of the competent sports authorities. We decline all responsibility for improper use
