A few very early ones had gear selector issues similar to the 675 STripple, if it's OK now it shouldn't be an issue. The first 18 months of production had a lot of indicator stalks breaking, identified as a sub supplier quality issue and replaced under warranty. The first year of production got a lot of complaints about it being easy to stall while pullback away, a revised ECU map was loaded at next service, pays to ask if the latest map is loaded as they do update them from time to time.
The stock can is very quiet and weighs about 6kg if memory serves me correctly, it will scrub up OK but there's a bewildering array of aftermarket offerings that weigh 2kg or less, from £250 upwards, usually benefits from having the TOR map loaded if you go that way. Stock they can give a "tok , ting, tang" (sounds a bit like a coke can going down a garbage chute) from the exhaust on over run, TOR map all but eliminates it.
Seats are personal, I never had an issue with it even on an 800 km day.
