An electronic-control throttle that is in fact a world’s first in being adopted on a production motorcycle, on the 2006 R6.
Yamaha Technology 1998: One-piece Plated Cylinder and Crankcase
A plated cylinder in a single-unit with crankcase made possible by rapid plating technology. Adopted on the first YZF-R1 and other models.
Yamaha Technology 1996: Forged Aluminum Pistons - Controlled Forging Technology
A technology for forged aluminum pistons and their mass production that enables lightweight design. First adopted on the ’96 model YZF1000 ThunderAce. Used since on large-displacement sports models from the YZF-R series to the Midnight Star.
Yamaha Technology 1987: Exhaust Ultimate Power Valve - EXUP
A variable valve system that eliminates “valleys” in the torque development curve in 4-stroke engines. With continual improvement since the first adoption on the ’87 model FZR400R, the latest version is used on the YZF-R1.
Yamaha Technology 1985: Aluminum Deltabox Frame
A high-rigidity aluminum frame construction that helps achieve outstanding handling stability. Adopted first on the ’85 model “TZR250”. Since then it has been adopted on important supersport models. The further evolved Deltabox frame now appears on the “R” series models.
