I am in love with Triumph! I have had 5 bikes one was a daytona 600 i liked it so much i bought the 650 and thats what i ride now until the weather gets better and then I will def be getting the 675. Triumph's are extremely comftorable they will keep up with any bike in their class and they are not a dime a dozen. I love anything on two wheels but the triumphs seem to hold my attention and a spot on my insurance more than the others.
I think the 675 looks better than any other bik in the 600 class. As far as power goes the extra 75 cc's doesn't give it any advantage at all in either hp or torque. If I was considering a 600 class bike the 675 is where I'd put my money. As mentioned above, they are less common and have far more coolness factor.
I always thought they had more HP and torque than the typical 600s. My buddy ran his last spring and went to a best of 11.02 in the 1/4. Is that what all the Kawasaki, Honda, Suzuki, Yamaha 600s are running too? With the extra 75cc I would think it would get it something over the 600s. Nonetheless they are nice looking bikes. I don't buy into the comfort factor, but then again I ride a naked.
My husband bought a 2010 Triumph Thunderbird. It rocks! It is so much more comfortable than his previous Honda Shadow. It has so much get and go that he has to be careful to not go too fast ... don't want a ticket.
