From REDS Racing:
REDS Racing is excited to introduce a new super powerful 7 ports on-road engine called 721 Pista Gen2.

What are the tech specs?

The new 721 Pista Gen2 engine features extreme power, high reliability and tuning stability. Combined with specific technical changes such as new carburetor, new cooling head and front bearing, this 7 ports engine features higher power and better fuel efficiency compared to any other engine. The new engine comes with a DLC Coated crankshaft and backplate for improved engine durability and power delivery.

What is new and different?

New 7 Ports Sleeve: New high torque 7 ports sleeve for great torque and power output. Basically, the new exhaust boost design combined with the inlet ports layout ensures an increase in power on the whole RPM range.

New high speed front bearing for increased durability and idle stability

Completely redesigned cooling head: lower gravity center for better car handling, improved aerodynamics for a lower drag and improved engine cooling, new design and colors.

New Carburetor and Venturi: Another big improvement is the brand new carburetor made from pressure die casting. The carburetor has been completely redesigned: new body mold, new internal fluid dynamics, new mid range needle, new high speed needle position.

721 Pista engine pro tuned is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside Reds Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards.
