Scarabeo 500 On A Dyno

Monday, March 9, 2009

Some of you may know about Micah Shoemaker as a master motorcycle-tuner and the owner of Af1racing in New Braunfels, Texas.  Recently, he had a chance to put a modified ’07 Aprilia Scarabeo 500 on a dyno as the video below will soon demonstrate: 

In the notes related to the video, Micah writes:

This Aprilia Scarabeo 500 has been modified with about all the bolt-on parts on the market. In terms of engine mods, they are very simple, a bolt-on Gianelli pipe, a Polini variator kit and a bespoke, owner-manufactured large K&N-style intake kit. This all had a net result of a 9-bhp or 30+ percent gain in power at 70-mph. The dyno test may look weird. It is a load test on a Factory Pro EC997 dyno done in 5-mph increments to make a full dyno graph of bhp vs. road speed. The engine in this scooter is the Piaggio “Master” 500-cc which runs in closed-loop mode of the efi system, therefore even somewhat “heavy” modifications like this radical solution to the intake (stock is very restrictive actually, kills all the noise and about 5-bhp) can be mostly compensated for. The addition of a modified Power Commander IIIusb or PC5 (also called PCV) could get another 1-3 bhp but the additional cost would be hard to justify. You see the pipe get red hot, this is very normal during dyno testing with thinwall stainless header pipes, nothing to be concerned over.

Great work, Micah!  For a closer look of this bad-boy Scarabeo, go here, here, and here.  I wonder if I could do that same air filter mod on my MP3 500 since it shares the same engine with the Beo 500?  Maybe after the factory warranty becomes void, huh?  Anyone interested in having his or her scooter dyno-tested? Micah at af1racing does offer this service for a fee, and you can contact him here.–Lorenzo
