    Downshift without clutch (WR 450)

    JasperC posted a topic in Dual Sport, Offroad Bikes
    Hi all. For our FSAE car, which runs a Yamaha WR450 engine, we are looking into a semi-automatic shifting system. We have had that for a few years now, but it has always caused us some problems. We always shift gears without using the clutch, nor throttle blip. We know that the problems probably originate from downshifting (upshifting shouldn't be a problem) but what we don't know is if we can solve it by regulating the system better, or if it is really necessary to use the clutch while shifting down. So I was hoping to hear from some owners of WR 450 bikes or similar, whether it is possible to shift down without the clutch. Does it require a lot of power from your leg? Or can you do it without a problem? I hope there's people around who can answer my question. Kind regards, JasperC
