Aprilia rs4 125 vs. Yamaha yzf r 125 ?

Hey guys, I’m thinking of buying a 125, the Aprilia rs4 125 and the Yamaha yzf r125 are in the narrow selection. I read in a test that the Yamaha has a top speed of about 130 km/h and the Aprilia is said to have achieved only 110 km/h. I can’t imagine that the only 110 km/h can do, they did the test on a mountain O.o ? In a video where they tested them on a track she has already made 115 km/h in the curves then I can’t believe she’s supposed to make it on a straight track just 110 km/h. Maybe you can help me if someone has one of them and can answer that would help me a lot.
