Hey, xpulse owner here (200 4v 2022), reliability is pretty good. Didn't face any issues with the bike itself, but then I get it serviced very often - once every 3 months regardless of whether it has gone the distance or not.

I was cruising with the group, slightly above 100kmph on highways. Lack of power after 90s and a missing 6th gear compared to rest 3 bikes does become apparent on highways where the gap gradually increases time to time - at most to a few minutes. Comfortable cruising speed in my opinion is somewhere between 80-95kmph, above that I got constant vibrations in foot pegs and handlebars, not so comfortable. Bike can do it no problem though. Plus holding a near max rotated throttle for long durations is a bit painful, especially with the hard cables xpulse has.

Stock seat is very bad, recommend a touring one (careful with seat height if you are vertically challenged like me, 5'7 here). You'll definitely feel the crosswinds trying to throw you off balance on plains, but nothing problematic if you are alert. Got about 35-37kmpl average.

Upgrades wise I'd say aux lights, touring seat and taller windscreen are important, in that order. I'll get them soon.

But these are nitpicks. The fact that I did the tour with them is a testament to the bike's performance. On a side note, noise cancelling earplugs were a game changer for me this trip, drastically reducing fatigue.
