Just to say my Kwaka W650 is a fantastic bike, which has been mistaken for a Bonnie a few times now. The engine is virtually bulletproof, the bevel is smooth and, whilst it can 'kick' a bit on corners, it's definitely no worse than the A10 (better, in fact, as it doesn't spray the rear tyre with oil).
You do get the usual for a 22 year old Japanese bike, bit of corrosion and engine casing tarnish, etc, etc. But completing my January 500m run it never missed a beat in frost, rain, cold, etc, etc. GB will, no doubt, back this up (as will others) riding a modern gives confidence of completing a big journey on the bike instead of on the breakdown truck.
This summer, I'm off to Dundee on the bike with a stop off half way there and back. Should complete around 600m/1kkm - do you reckon the run-in Beeza or the Kwaka??
