Awesome - and thanks for the kind comments
The Performance Pack makes a very significant performance improvement over a stock bike - it shaves something like 4.5 seconds off zero to top speed time and addresses all the weak links in the bike at the same time
So the acceleration rate is greatly improved.
One thing that I think people don't pick up enough on is re-sale value. There is no reason why a person should not be able to recoup the cost of the Performance Pack (and probably more) during re-sale. The difference between a stock bike and one with the Performance Pack is dramatic. If someone is shopping for a CBR 125 (and lots are) it's a very good way to make your bike stand out from the pack because people can't help but notice the increased performance.
BTW, bear in mind, prices on the site are in Canadian dollars, there's no tax, shipping is at cost, and typically there are no duty fees or taxes upon arrival. On top of that, we have full HD installation videos to help you install everything
