It's simply not realistic to make major changes every year, or every other year. The fact that Yamaha focuses on any changes at all is good. From '04 to '05 there were suspension upgrades. Gen I to Gen II came after 6 years run on the production line. Hopefully, with the increased sales, the FJR sales will pay for an earlier retooling of production lines.
Even a small change can cost a tremendous amount of money if the production line has to be modified. It isn't just the redisgn of the new part, but the start up costs of manufacturing that part. Then add in the start up costs of mofifying the assembly line and training all the workers. Also add in all the testing required before they can release it for production. All this costs serious cash. Luckily, the Japanese seem to focus on agile production line techniques rather than highly automated techniques. Nonetheless, there is a financial formula around how often they can redesign and retool the production line per design revision so that they remain profitable. If they lose money on the product, they stop producing it and I think none of us want that. Many of us are already thinking of our 2nd and even 3rd FJR (or 4th even?).
Even Honda Accords are only redesigned every 3 years and they sell quite a few more boatloads of them than Yamaha sells FJRs.
I'm just glad they didn't waste any of the good colors until the Gen III is released
