Yep.
The CR difference could be as simple as somebody doing a typo on a marketing news release. The 4hp difference could be explained by a dozen different things. Besides it is 4 bloody HP not 40. The rated HP is just a numbers game at the best of times since that is not even close to what is actually going to the wheels.
It is only meaningful for bench racing and even then it is questable since not all manufacturers use exactly the same methods to get their rating. Most are done on an engine stand in a climate controlled lab under perfect conditions that nobody will ever actually see on the streets. There is an ISO Standard they could use but there is nothing that forces them to use it.
If the 4HP is that big a deal to people they can just add in an auxiliary engine!
