This hypocharger came with my 650 classic along with BUB pipes.Was woundering what advantage it has over the stock air cleaner system? It does look bad ass.

If it is a working hypercharger it is used to get more air into the engine. It has a high performance air filter like a K&N and has a larger air intake area. More air, generally more power. To get best results of a HP gain you have to rejet the carb/carbs (or if EFI add a power command module of your choice) to handle all that nice new air flow correctly, and keep the engine from running too lean. Adding a new exhaust takes all that air coming in and lets the engine push it out easier. Voila more power.

Reason I said "working" is the Stratoliner has it's air filter under the tank. Kuryakyn has a pseudo hypercharger kit. It's just for looks. :D

There isn't a lot of latent HP to be gained with intake/exhaust modification on a 650....but there is some. Over the years we've seen gains with a Hypercharger and it's definitely better than the stock set up on the 650.

As mentioned above, it just lets a little more air in....coupled with a decent exhaust...you'll get a few more horses.
