Ielasi Tuned ‘Pista’ .21 Onroad Engine
Having announced their new 2025 engine range earlier this weekend, Ielasi Tuned has unveiled specific details about the new ‘Pista’ .21 Onroad engine. This engine is the result of over a years work with their entire team, and which culminated with victory on its debut, securing P1 and P2 in qualifying, and P1 and P2 again in the final at the recent ENS race with team drivers Simon Kurzbuch and Toni Gruber. Starting with the name, Ielasi Tuned decided to discontinue the “GP9” series that existed since the beginning of this collaboration with O.S. Engines to send a strong signal of a new beginning. Produced entirely by O.S. Engines but now 90% from Daniele Ielasi’s designs and directives, only the crankcase and the carburetor body are in common with O.S. – everything else about the engine is exclusive to Ielasi Tuned. The new Pista engine differs from the previous GP9R24 in many details. The top needle/holder on the carburetor is entirely produced by in-house, no longer by O.S., as they have decided to go their own way, focusing heavily on ease and precision in engine carburetion. A new bottom needle produced by O.S. greatly optimises acceleration at low revs. The Pista gets a new exclusive Ielasi Tuned underhead by O.S. as well as a crankshaft optimised with Ielasi Tuned timing. New 2025 version piston and cylinder gets a new inhouse finishing process using a new technique that has improved ease of break-in, almost minimising the problem of scratches while maintaining a coupling and compression hardness that lasts over time which is a major improvement on the past. In addition option parts include a new Ielasi Tuned connecting rod and a Swiss made WIB Ceramic Bearing.
