Description

Spears Racing have developed new, innovative Yamaha FZ07/MT07/R7 Velocity Stacks.  This innovative  revolutionary revolutionary design is backed by real dyno testing and our Corbin Custom Design engineering staff.  Our Yamaha FZ07/MT07/R7 Velocity Stacks will improve torque/HP and smooth out power delivery.  This allows the rider a truer feel for the throttle which enables more accurate throttle input, improves confidence to get on the throttle sooner and boosts rider confidence. The OEM Air box of the stock “commuter bike”  Yamaha FZ07/MT07/R7 contains two velocity stacks and a small intake/air filter inlet which severely limit the air intake into the engine.  This kit replaces both stacks with our own Spears Racing shorter velocity stacks with new intake manifolds and air filter inlet to fit into your  current OEM air box.  These shorter velocity stacks not only allow more air into the engine, but they also smooth out the increased flow of air to really maximize the benefit.

The performance difference with the Spears Racing Yamaha FZ07/MT07/R7 Velocity Stacks compared to the stock is dramatic.

Here’s a dyno comparison with a 2016 FZ07 stock engine(OEM) with a stock ECU/Yoshimura Exhausts System verses a stock engine(OEM) with a stock ECU/Yoshimura Exhausts System a MWR Air filter with Spears Racing’s velocity stacks and air filter inlet. You can see the power band carries strong through the complete power starting at the 4000 RPM’s and continues to pull to 9600 RPM’s and continues to do a complete sizeable separation to 10,500 RPM’s instead of falling off like the OEM Air box set up and we don’t lose any important midrange power. The increase from 8,000 to the rev limiter is massive increase in both Torque.

 

There is also a dyno sheet we have that shows the difference between the Spears Racing Velocity Stack kit and a Know USA developed system, The Spears Stacks make more low end and top end than its competitor (this was also done By our third part race shop)

*** All dyno results shown were done by a third party/Race shop located in Canada, Acme Motorsports owner Craig was chosen because of his dedication to racing and to the Yamaha FZ07/MT07***
