Hi
I have 2 xt660r both 2007 reg bikes, I also ride a fireblade 929, and an Fz1n. I bought the xt660r for some short distance fun. I can honestly say they may not be the fastest bike on the road but are lots of fun. I have one with all the mods and one 100% standard. Both ride with no faults at all. As long as you look after them. And service them regularly. You should have no problems with them. Just make sure it’s a good bike to start with. Was out on mine ( wife on other one) yesterday did 150 miles on the twisty roads and they are just perfect for it. Was out one the cbr 929 the day before and have no problems going from one to the other. The xt660 will sit at 75 to 80 mph no problems at all. They will do 100 but no point. Only thing I would say I would not want to do a long time on a motorway on one, but other than that I don’t have any issues with them at all, some people say they are jumpy in traffic and so on. But if you know how to ride you know how to ride after all it’s a single and they ride different to a in line 4.And to be honest I love riding it. Just remember it’s not a race bike so if you like doing 100 plus these are no good,but if you just like to go out and stick to or just over the speed limits these are grate, one thing I will say if you are going to ride it in the wet make sure you protect the engine paint with ACF50. Both my bikes still look brand new one has 7000 ish and the other 6000 ish miles on them both in showroom condition. 1 and 2 owner bikes. I would stay away from high mileage bikes An less they are cheap. And you really want a good service history. As it’s a big single I change my oil and oil filter every 1000 miles or every year what ever is first, over the top I know but that’s what I do. As long as the engine has been serviced regularly they are pretty bulletproof. The xt660x has a better riding position for me. There is something just not right with the XT660R riding position nothing you can not put up with I just find my back hurts / aches a bit on it after about 60 miles. I find the riding position makes you slump or arch your back a bit to much. but I had no such problem with the xt660x ,and I have no problems on my cbr or fz1 ,just the xt660r Hope this helps. Ps I will keep my two xt660 for years they will not do 1000 miles a year but have to have one in the garage ��
