The power figure give is optimistic, even in our best dreams we think of figures lower than that, so no idea as to wherre they got that number.
Stock my bike could get to 127 km/h, due to the Australian restriction.
Once the restriction was removed my fastest GPS reading has been 172 Km/h on a very nice long and straight private gravel road.
Unfortunately due to a desire to keep my license
, I have not tested the maximum pavement speed, but it does seem reasonable to me that that speed could be achieved at close to red line rpm in good conditions.
