To meet the wide range of rider needs, HFT offers a selection from two fully automatic shifting modes—D mode for ordinary riding and S mode for a sporty riding experience—or the 6-speed manual mode, which gives riders the option of riding with a manual transmission feel. The HFT creates a unique riding feel.
Characteristics of the HFT
A transmission system with a wide range of functions in a single unit, the HFT is a compact and variable transmission system encompassing functions for starting, power transmission and shifting, all on a single shaft. The basic configuration of the system consists of an oil pump for converting engine power into hydraulic pressure, and an oil motor for converting the hydraulic pressure back into power for output. Both are made up of multiple pistons, a distributor valve and a swash plate for piston operation, while the cylinders are integrated into the output shaft, forming the characteristic structure of the HFT.
The HFT also features the world’s first lockup mechanism for an infinitely variable hydraulic mechanical transmission. When cruising, this lockup mechanism works to minimize transmission efficiency losses, contributing to improved fuel economy.
At last, avbout the « second » heart of this engine, its engine, the DN-01 will be powered by the well known 680c V-Twin of the Dauville, also featured in the new Transalp.
