Irrespective of the debate over time between model succession, to me it's very clear that the SX series of cars were pretty similar in design and many of the parts were carried over, but each new design gave an increase in performance.
I think what we have now in the K1 is the start of another line of cars with twin belts, which seems to be very quick going by Toms performance at Area51. Maybe they will do a US spec kit with big bores, who knows, especially as Schuey do seem to be paying more attention to the US market.
I can't wait to get my K1 on the track, just waiting for the shell to be sprayed.
