I have a K1 750 and love it.Owned it for 5 years .
I can do very long journeys without any real fatigue although i do get the usual sore knees on a long run (I'm 6'2),the seat is well comfy and I dont get back ache or bum ache even if I've been riding for a couple of hours.
I us it to commute to work as well as the odd blast on a sunday,and the odd trackday.I came off twice on track and it's no as pretty as it was but I still love to ride it hard.
I have had no problems with it, apart from the battery dying, and its now done nearly 20K .
Fitted with a Power commander, K&N and sport can I have had it on a dyno and the power output is around 135 at the wheel, also fitted a smaller front sprocket for more acelleration.I also fitted a scottoiler,I know people wonder why but I'm still on the origional chain and rear sprocket, the oiler sure does extend the life of the chain and spockets, well worth the money.
META alarm/immobiliser.
It still brings a big smile to my face every time I ride it.
Service itervals are 3.5K ,dont know how much they cost at a dealer as I do my own, rear tyre last's around 3.5 - 5K depending how I ride ,Front usually around 5k.
Best tyres I fond are Bridgestone BT014's.
I have tried Michelin pilot sports and Pirellie dragon evo corsa's.
You wont believe the diference going from your SV, a mate of mine had one and I've ridden it for a good few miles ,a very good first bike but I found the bikes limits fairly quickly , the gixers limits are far harder to reach, very stable and flickable in the twistys and damn fast on the stright bits.
If you wanted a test ride you are welcome to have a go on mine
