The top needle/holder is entirely produced by us in-house, no longer by O.S. as we have decided to go our own way, focusing heavily on ease and precision in engine carburetion.
New bottom needle produced by O.S. which greatly optimizes acceleration at low revs.
UNDERHEAD
New exclusive IELASITUNED underhead by O.S.
CRANKSHAFT
New IELASITUNED timing optimized for the new engine by O.S.
PISTON/CYLINDER
New 2025 version piston and new 2025 cylinder by O.S. but compared to the past, the super-finishing process for both is carried out in-house using a new technique that has improved ease of break-in, almost minimizing the problem of scratch while maintaining a coupling and compression hardness that lasts over time like we have never had until now.
