The Yamaha FZ / FZR’s came out in 2009 and as with all PW’s the need for speed by the customer becomes great, so now’s a good time to start thinking about modifying them by making them go faster and handling better. As I’ve now been installing a variety of parts to these machines over the past two years I’ve got a very good idea of what works and what doesn’t. What I’m going to do in this article is rather than listing a whole load of parts, I decided to put a kit together - the best performance package all in one.

Words and pictures: Nick Dyer.

As with all 4 stroke engines, one of the main ways of getting extra performance is by getting lots of cold air into the engine...so first things first, lets look at performance parts which will give us lots and lots of cold air.

The Riva Power Filter Kit replaces the restrictive standard air box and also provides a nice clean flow of air through a 4” composite tube. The filter is a huge K&N affair that also comes with a water repellent pre-filter. This is a fairly easy kit to fit with a small amount of mechanical knowledge and comes with some very good instructions. £279.00

Next up is the Intake Manifold Upgrade Kit. This little beauty is an inexpensive modification that you can make to your FZ. Inside your intake manifold is a small mesh element, which is quite restrictive when trying to ram as much cold air into the engine that is physically possible, so by removing the mesh you can increase the pressure of air by 1lb. Now this may not sound much but lb for £ this is a great modification. The kit is a billet tapered sleeve which fits directly into the hole that is left behind when removing the mesh element. In test it was found that the ECU will compensate for the additional boost. £34.00
