I was visiting with the dyno man from Bikeman the other day and asked the same question. He says the new Boyesens make more midrange power than the VF3 but VF3 has 2 more HP on top. That is different from the way it almost always used to be. He also said they are running the Boyesens in a test mule that will most likely get over a thousand miles this season. I will be checking back with him to see about their durability in the spring.
