Just been offered one of these (K1, 2001, Y reg with just over 4.5K on the clocks) for £4000 inc 3 month warrantee. What I'm wondering is: 1) What's the difference between a K1,K2 and K3. Are all 2001 models K1s? 2) Is this a good deal? It seems in pretty good nick but has had the right hand side lower bit of fairing repaired. Apparently it was a small drop which left only cosmetic damage. The repair hasn't been done perfectly but without looking closely its fine.
