That is excellent information, thanks again, great to have your input. Good to see you have had such reliability, my fears are lessened then, despite a handful of bolts falling off in first 100 km, three batteries etc! Mine is indeed the RT so I shall do as you suggested and get the 35T. Would you give me the dealer's email address please and I shall enquire about getting them to send me one. I am a bit disabled with a few crushed vertebrae which is why the bike has only done 450km in a year. This will rise as I get going more. Thus the freeway trips will be only very occasional and the off-road even less. I do intend to ride this thing more, and as I get used to it my confidence is growing - in my position and living in the countryside I can't just call a taxi or walk home if it breaks down somewhere.
I find it a wee bit squirmy on the back end on tarmac, sort of slides a little if it hits a bump or even finds the camber and especially if I shift my weight a little from cramp or whatever. I am getting used to that, probably happens because of the 'off-road' setup and because I learned years ago on road bikes. Do you have any thoughts on changing/adjusting springs?
