October 2007 Honda Press Release



It's certainly a well designed and engineered bit of gear - ha ha - otherwise known as hydrostatic drive. I first became familiar with it in the mid 1980s when working on new models of IH combine harvesters which were introduced at that time.

Many machines have this type of transmission these days, even ride-on mowers. Unlike motorcycles, they run at constant engine RPM whereby ground speed is controlled by the operator moving the hydraulic motor swash plate with a control lever to change speed. It was because of my prior knowledge and experience with hydrostatic drive that I got my Dino. 😁

Thanks Alexandre. I like the drive mode and gear chart on bottom of page 9. Then the basics of the lockup mechanism on pages 10 and 11. I think the hiccup felt at about 51mph (83 kph) must be the lockup mechanism engaging or disengaging in Drive Mode. With manual mode gear 6, I don't experience the hiccup (unless this is my imagination!).

You ARE quite right! A few years back, we had someone (on here) who said the 'hiccup' was due to a fuel metering problem in Drive mode and 'corrected it' by messing with the programming.

Today I tested the hiccup (pronounced 'hicky-up' /sarc) more thoroughly and confirmed if in 6th gear manual, it does not occur when either going faster or slower past 50-51 mph inflection point.
Here, I owned this bike all these years and never gave the hiccup much thought; it was noticeable but not super annoying. Now I get to 6th gear manual mode sooner to keep the lockup mechanism from bowing out like it does in Drive mode. (Sometimes even a blind squirrel can find a nut!)
