ADVANCED CARB SYSTEM:
The revolutionary carb features a differently positioned top end needle, rather than pointing diagonally upwards, it is now horizontally positioned much lower down. HCX Horizontal carb main features: higher idle stability, more precise tuning, easier access to high speed needle, higher mid/top range power.
LIGHTWEIGHT & LOW GRAVITY CENTER:
We designed the new REDS Factory Tuned line to be not only more powerful and reliable but lighter and with lower gravity center than ever before. To do that, we couldn’t just shave a millimeter here, a gram there. So we started from scratch, redesigning each essential part like crankcase, cooling head, combustion chamber and Black Diamond coated backplate.
HANDMADE, TUNED AND ASSEMBLED:
The R5R Racer is hand-tuned 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. This is core to the values that makes the R5R Racer different from any other engine brand on the market.
R5R crankshaft is surprisingly strong and reliable thanks to our special steel and heat treatment.
Our special silicone filling reduces the inertia to rotation.
