Ours was one of the early 2010 RSV4Rs that underwent an engine replacement due to a connecting-rod recall, and there have been a few issues that hint at that. The swingarm pivot nut was found to be under-tightened, as was a radiator hose clamp, which allowed coolant to leak. At one point a fluke intake-pressure error code sent the bike into Level II “limp mode” halfway home from work, limiting speed to about 40 mph. The only other problem was a progressive one: Over the past 1000 miles it became increasingly difficult to find neutral. Ace Aprilia technician Alex Franz diagnosed the problem as a loose shift-shaft centering pin, which is a rare issue that has only occurred on a few hard-ridden bikes. If your RSV4 is less than two years old and develops this problem, the repair should be covered under warranty.
