'98–'01 VFR800 (5th-gen)

So, how would you like to add 50-60% more power to your VFR?

There is a reason you own a 5th-gen — it's unique amongst bikes, and you love that. The V4, the single-sided swingarm, those gear-driven cams, the sporting yet refined nature, the RC45 derived powerplant, etc. etc. It all adds up to one legendary package.


However, the output for an 800cc engine is a bit, well, lacking, especially compared to modern day standards. When a recent 600cc sportbike can trump that awesome V4 in the power department, something is wrong.


Enter the A&A Performance Supercharger Kit. Without changing any major internals, and with the ability to perform the installation yourself, you can have a bike that will keep pace with brand new liter-bikes for less than half the cost. Best of all, you retain all the rideability you currently enjoy, but with signficantly more oomph should you feel the urge.

This is the real deal...

This kit is not some thrown together mess of parts; it is a thoroughly engineered, road tested and tuned system that has undergone 2 years of development. It is meant to be installed by the average enthusiast and will increase the power of your bike by a legitimate 50-60%.


While certainly not meant for beginners, the power produced is remarkably controllable and instant in nature. Thanks to the vacuum operated bypass valve, part throttle cruising and light acceleration are unchanged from stock and gas mileage is only affected under heavy acceleration.


With nearly silent overall operation and the ability to hide under the stock fairings, the installed kit is virtually indistinguishable from a stock setup. Low maintenance requirements and choice component selection ensure reliable operation for years to come, along with more guaranteed smiles per mile than anything else you can buy for your bike.


What else do I need?

All major components are included, with the exception of a Power Commander III (required for tuning). It is recommended that any parts in poor shape be replaced, and vital fluids (oil, coolant) be changed as well.


You will need basic sets of metric & standard tools (screwdrivers, sockets, open-end wrenches, hex keys), a torque wrench, cutting shears, files, pliers, a 15/64" drill, and a 1" deep-socket.


While certainly not necessary, an aftermarket slip-on exhaust will help your hungry engine produce even more power acoss its entire powerband. A boost gauge is not included, and component polishing is available upon request.


The Bottom Line

If you love your bike but catch yourself eyeing newer machines sporting greater power, this is the mod for you. With this kit, you retain all the benefits of owning a VFR without dropping a fortune on a new bike, plus you get the perks of piloting a supercharged motorcycle — definitely not an everyday occurance in this run-of-the-mill world.
