Hi Lyn, the post I got the link from was recent, so it fooled me into thinking it was a fairly recent problem. I think it was actually 2006.. I take it you'd recommend the F650? I've never owned a BMW but this one appeals as simple, rugged daily transport. I'll have to have a look at the price of parts on ebay etc.
I loved mine, 650 Rotax motor..water pump IS the only thing that ever gave on-going trouble. I had two and bought a spare kit to carry on my Euro trips. A bit lumpy the motor but big singles always are, as said great bike but getting on in years now. If you could find a low miler from some old guy would make a cracking commuter, no one would nic it cos too old.. got about 60mpg. I used to change the chain and sprockets together also cush rubbers or the gear change got a bit hard..Even the OE battery lasted 8 years. OW! head bearings were made of cheese when they were in production so they were changed to SKF and no more trouble. Oil in the frame was a pain to fill up.
Freewind is a very good bike, bit weighty..Pegaso with Yammy motor also good, i look after one for Tonys mate. I have had to put two rear master cylinder on it in three years, the last one i bought a cylinder from an off roader can't remember what now, not had another problem..The off road cylinder had a lot more meet on it and i could machine the mount to sit correctly as the OE was sat out of true and the push rod was pushing of center.
Strangely, I've always fancied the Freewind after reading a road test in the old "Used Bike Guide" must be 10 or more years ago, it came across as a decent bike, and for the same reasons the Pegaso (Strada?) with the Yamaha motor. Both simple reliable big singles which sound like great fun to ride. I was out and about a few days ago and a big single accelerated past (I didn't see it just heard it) with a quickshifter on and it sounded awesome. Reminded me of my old SV1000...
