Music for bikers: Honda Fireblade

A friend of me ownes a Honda Fireblade with 170 hp. Currently he is working in Russia and he asks me to record the sound of this bike to be able to listen to it sometimes :wink:
Later, i had the idea to create some musik as a combination of the sound of his engine and some harmonics. This is work in progess but the first part is almost completed:

I created it with Ardour and Hydrogen. Comments are welcome.
