Ultraviolette F77 review, road test

When you put the bike in its top Ballistic mode, the fun that can be had with its energetic acceleration is very addictive. To give you an idea of just how quick the bike was, in our roll-on acceleration tests, the F77’s figures were more or less in line with the Kawasaki Z650RS! This isn’t entirely surprising when you factor in the 95Nm torque figure, which is more than the Street Triple 765, for reference.

Winglets serve to cool the battery, motor and act as crash protectors.

While acceleration from a dead stop is a little sluggish (UV has purposely done this to make the bike less intimidating), once you cross the 20kph mark and twist the throttle, it takes you merely a handful of seconds to cross the 80kph mark. After this point, acceleration trails off dramatically  as you cross the 100kph and 120kph thresholds. While the 145kph electronically capped top speed is nothing special, the awesome roll-on acceleration makes this bike a thrill like no other in the city. The F77’s huge 10.3kWh battery meant that this was the first two-wheeler where we adopted the car team’s methodology for range testing. We ran it from 100 percent to 50 percent SOC while logging the odo at every 5 percent SOC drop.

Tactile and intuitive switchgear is borrowed from the TVS RR 310.

This was done in the lowest Glide mode over a combined cycle, including fast-flowing roads as well as congested traffic, simulating both city and highway conditions. Extrapolating the data, we arrived at a range figure of 221km on a full charge.

In Glide mode, acceleration is quite neutered, but even so, we were able to manage a speedo-indicated 92kph, although acceleration after 80kph was very sluggish. I also noticed that when climbing a flyover, if my speed was above 75kph, it would drop by a couple of kph, but once I was back on a flat surface, it would climb back up again. Still, Glide mode is perfectly usable in the big city, but with a bike like this, you want to spend all your time in Ballistic mode. Doing so will have the range drop far more significantly and you’d get closer to 150km of range if you ride flat out all the time.
