I dont own one but my most frequent riding partner does and Ive ridden it. I have a 600R Renegade so thats what I compare it to. the 650 is a stout performer, strong midrange. We never lined up but I'd guess its faster than my 600R. Biggest improvement over the Poo 600's is definitely the fuel and oil consumption. We ride the same and I was consistently getting almost double the fuel mileage on my 600Etecs as he was on his last 4 or 5 Poo 600's. The 650 is very close to the Etec. I would buy one.
