I hate the 4 cylinder buzziness and there is a ton of engine heat, seat gets very hot and the black tank gets scorching hot, I used to have a 2008 Versys and enjoyed the parallel twin, also I am not enjoying the Versys 1000 extra weight, I think I made a mistake oh well, any thoughts, am I crazy?
Not sure how you're riding it, but when I'm moving I don't notice any heat. What is there in stop and go traffic is no worse than anything I've ridden with an engine for quite some time.
I too was a little dismayed at first as the reviews were talking about buttery smoothness and mine felt like a typical inline that buzzed at various places in the rev range. It was never troublesome, just a minor annoyance. As the bike has broken in, it's become much smoother. Basically not noticing any vibs until ~6k rpm and then only for a short spurt and its pretty smooth up to redline. In fact, it's so smooth I often bang it off the rev limiter because I have no visceral cue to get me to shift.
I think weight is a non issue. You bolt all the bags, hand protectors, center stand etc to the 650, it will weigh just about the same as the V1K. Similarly, if you want to lose some weight, just start taking that stuff off.
Someone mentioned that the V1K shares nothing with the V650 and on that I disagree. Maybe the parts have different numbers, but they share the same height, riding position, and looks as one another. I'm sure there's a whole bunch of commonality between switchgear, lights, wheels etc. To me that is every bit as important as whether or not one makes more power.
Do what ya like, but I'd guess you're going to take a beating on that trade.
