Custom Bike Question
 

This bike is made by the famous british company Triumph. It sits on air ride suspensions and has a three cylinder engine. This is all I know about it and I was hoping if you all could tell me anything you can about this bike like what it was made for, how fast it can possibly go, and what exactley is the purpose of air suspension? Thanks!

It is hard to tell by the photo, but it looks more like a car engine, not their motorcycle engine. I'm sure if geared properly, it would exceed over 150 mph easily. The air suspension has the ability to adjust for ride height as well as a kick stand when deflated.
