The Gen 3 Suzuki Hayabusa uses extremely long and thin factory velocity stacks to slow down the airflow for immediate torque and daily riding response. Unfortunately, this kills the racing range of horsepower. With higher RPM the engines nods off soon and loses nearly 30HP as you rev it out to peak RPM. The BT Moto modified velocity stacks gives you almost built cylinder head power gains in an easy, bolt-on, plug-and-play package using factory hardware and air filter (optional).

WHY FOCUS ON TOP END POWER?

We decided on this design because it mimics what every part / aftermarket exhaust does to this platform, which is move the powerband to the right. The engine has tons of torque and displacement but absolutely just no legs as it’s revved out compared to its 1000cc brothers. The velocity stacks equalizes this and gives the Hayabusa the advantage it needed to be competitive again.

We studied the other velocity stacks on the market, and some were too tall, too short, or simply didn't fit the factory airbox.. some even came apart with mileage (yikes). Since the Hayabusa isn’t a big tune only power gainer, we knew we had to bring a hard part to complement our ECU flash.

We spent a lot of time building a design that captures more air at high rpm and high speed to fill the throttle bodies versus tuning it for low RPM cruising response. Our box filler design maintains a flow where no air gets trapped in corners of the airbox at speed to maximize the powerband under ram air pressure. The low rpm losses can be minimized with careful throttle and fuel tuning.

We highly recommend these with our flash as it’s the best bang for your buck modification for the platform.

BT Moto velocity stacks are developed and designed TO WORK WITH BT MOTO CUSTOM FLASHING. Flash adjustments include revised tuning for BT Moto custom velocity stacks. *VELOCITY STACKS DO NOT REQUIRE FLASH PURCHASE BUT IT IS RECOMMENDED FOR ADVERTISED RESULTS*

BENEFITS:

• With our flashing, there's no need to worry about fueling or rideability.
• Correct fueling on both banks in “Alpha N” mode and race modes (comes with flash).
• Engine tables corrected for BT Moto velocity stacks (comes with flash).
• Custom velocity stack designed for YOUR airbox. No one size fits all approach.
• OEM fitment and ability to go back to stock when ever you'd like.
• Gain 20+HP (depending on bike and mods) at higher RPM's (with BT Moto Flash).
• No power loss in low or midrange (with BT Moto Flash).
• We've tested all the others on the market and this one has the best power hands down!

BT MOTO VELOCITY STACKS:

Custom composite with our logo etched into them, the BT Moto Velocity Stacks have been carefully engineered and designed to maximize power in the higher RPM range while not losing power in the low RPM range (with ECU flash).

Made for an OEM fit, the BT Moto velocity stacks bolt to the airbox to ensure tight fitment while also being easy to install. These are plug-and-play and require no additional modifications to your airbox to fit. Simply remove your factory velocity stacks and install. Coupled with our custom flash, the combination makes an extremely easy install and tune that can be done in your own garage, with basic tools and minimal mechanical knowledge.

DISCLAIMER: FOR CLOSED COURSE COMPETITION USE ONLY. PENDING CARB APPROVAL. NOT INTENDED FOR STREET USE.

DYNO PROVEN

The dyno results below are from a 2022 Suzuki Hayabuya tested at our facility in Massachusetts. This bike has no modifications (other than listed) and is on 93 octane pump gas. You can see gains through the entire RPM range from down low to up high. The deeper the bike gets into the RPM range, the more power you get, at redline we gained OVER 50WHP. You can see the stacks make a lot of power up top with clearly no losses down low. Results tested same day, same dyno, back to back. (See image gallery for dyno chart)

Factory Tuning, 93 Pump Gas: 170 whp / 103 wtq

BT Moto Stage 1, 93 Pump Gas, BT Moto Stacks: 187 whp / 109 wtq

BT Moto Stage 1, MR12 Fuel, BT Moto Stacks: 197 whp / 114 wtq

The dyno results below show the before and after results of our stacks ONLY. No other modifications or ECU changes shown. This represents how much room for improvement the stock stacks left. Without tuning there is a small loss in the mid range, but up top where it's most important, our stacks gain 20WHP. Again, this is completely stock ECU with the addition of our stacks only. (See image gallery for dyno chart)
