In motion, the Sixty does feel a little tamer than the full-strength model but it’s not a big gap. Indian has given the Sixty, like the large Scout, very progressive throttle action through the ride-by-wire system. Unless you’re just not paying attention, you won’t get caught out by the bike’s reactions to throttle and clutch takeup. It pulls off the line cleanly but needs a lot of throttle-grip movement to extract all it’s got. There are no lumps or bumps in the power delivery, either, just a nice, linear-feeling torque curve that tapers gently to the rev ceiling. This modern, counterbalanced engine is very smooth below 4,000 rpm, picking up a trace of high-rpm shimmer above that. Indian’s tactic for changing from a six-speed to a five-speed box involved simply removing fifth gear. The Sixty’s ratios in fifth are the same as the larger Scout’s in sixth, and while the ratio gap from fourth to fifth is noticeable, it’s not a practical issue. As before, you’ll be happy up to 75 mph and still unperturbed by 85 mph, but beyond that the Sixty’s engine starts to feel buzzy.
