Hello, new guy here, and have a few questions. On a totaly stock bike.
1. In top gear what RPM does it run at at about 100 km/hr approx. 62 MPH?
hard to say for me (I have a 16t front socket, but I'd guess around 5KRPM
2. How is the vibration at about 100 km/hr?
very subjective, depends what bikes you've ridden before and what you are prepared to tolerate. I don't think its an issue, yes there is vibration but its a parallel twin its part of the bike. its not significant for me, but Its soemthing you'd need to judge yourself
3.Average range on easy highway rides per tank of gas?
200..220miles (320..370Km) with some to spare (last trip for me was 56MPG, which is around 5l per 100k)
4.How is it ergonomically for a 200 pound guy, that is just under 6'2" tall.
shoudl be fine, but do a test ride to make certain it meets your requirememnts
5. Any issues with a 200 pound rider, and 120 pound passenger?
doubt it, Im 240lbs and did an extrended trip earlier this year 6,000 miles in 4 weeks
6. How effective is the windshield at highway speeds?
depends on what you expect from a screen, its does an adequate job, its never going to be as good as an RT or simialr with an adjustabel screen, but its OK. you may need to tinker with the height or upside down or get an aftermarket screen. screens are very personal. the stock screen will cut through the wind and provide a turbulent free area for some people (either very small who duck below, or the tall who let the windbalst hit thier chest & shoulder area
7. Is the seat comfy for a 4 to 5 hour ride?
not sure I'd want to do a 5 hour on the go, have done several 300 mile+ days (2 500+) so high mileages can be done, but you'd probably want to acclimatise your butt before doing long distance. you are going to have to get of occasionally to refill.. I reckon thats every 3...4 hours or so. however one guy I know has done 1017 miles in one day on a stock seat (think he had a gel pad for that ride though.
