On the Dyno
Since this is such a new engine, we had to work a little magic in order to get the test done. While we normally use Dynoport's facilities, we were forced to turn to the factory for a helping hand. When the F7's actually roll off the assembly line, we'll put one of those on the Dynoport bench as well.
Our factory dyno test of a final-stage preproduction motor showed the new 698cc laydown twin runs just as strong at the top end as the 800 standard motor, but with a longer, broader powerband. While it doesn't match the bigger sled's numbers all the way up, our seat of the pants testing showed that the Firecat's significantly lower weight allows it to get up and go much quicker than the traditional ZRs.
At 140.1 factory horsepower, the F7 EFI will certainly be the toughest 700 single pipe engine we've ever seen, if it comes off the production line in the same shape. Time will tell, but we've got a good feeling about this one.
