I don't think under inflation would change the diameter enough to throw the speed off that much. In my case the diameter of the 14" wheels is noticeably less than the 15". I see that in the spring when I'm going back to the 15". If I jack the car up enough so the 14" leaves the ground and I can remove it sometimes I have to jack a little more to get the 15" on. The explanation I've heard for the Japanese bikes is people tend to play with different tire types and the bike manufacturer has no control so they throw in a margin of safety so they can't be blamed for the 'but the speedometer said 100 kph' argument to try to avoid a ticket. Believe the speedometer and you'll always be a little under the limit. There might be a little marketing involved too. My DR650 would need to be going downhill with a tailwind to break 160 kph despite the optimism of the speedometer. Oddly the speedometer on the Harley is dead on. The odometer/trip meter is LCD and only visible on hot days. (the bike is 28 years old and like me, things don't work like they used to) so I mounted a bicycle speedometer and glued the magnet to the wheel. I can dial that in by setting the circumference. I don't know why cars don't have that option since the speedometers aren't mechanical anymore.
