Very nice! Thanks for that infoIf i recall correctly only 2000 were made for each year (03 & 04) so like 4000 in total. 2000 is the number needed to homolagate them for racing. 2000 street models need to be sold to race them. I know for a fact that Kawi lost money with these bikes as they came with a completly higher spec than the 636, but Kawi did not care as it was needed for racing and they still made tons of 636's. It's not just the engine being 599cc, the frame is slightly more aggressive (tighter rake) and they all have an excellent slipper clutch. They 04's went a huge step further by adding forged pistons, bigger valves, high-flow head, twin injectors, etc. The last 4 digits of your vin# is the production number out of 2000. For example #483/2000. These bikes are quite rare compared to the 636 as most went straight to the track and some people did not even know what they had. They were $1,000 more expensive than the regular 636.
