BT Moto (23-27) Kawasaki ZX-4RR Stage 1+ Performance Flash With Tuner

MAKE SURE TO REVIEW THE TABS ABOVE: HANDHELD, DYNO RESULTS, RESOURCES AND MORE INFO!

The ZX-4R / RR is one of the most requested products we've had this year. Customers are very excited to see this bike unlocked and we were the first to finish this project for the community. We want to make sure that people are not only satisfied with our flashes, we want them to be amazed with the results. After taking some time to develop our mapping, we think we have something everyone will be happy with.

WHAT'S INCLUDED WITH STAGE 1 ZX-4R / RR FLASH

• Fueling Adjusted (per gear)
• Ignition Adjusted (per gear)
• Throttle De-restricted (per gear) +15hp
• Lower Fan-On Temp
• Increased RPM Limiter
• Removed Top Speed Limiter
  

THE DETAILS

• FUELING - With custom tuning we can target better AFR (air/fuel ratio) plots to enhance not only racing performance, but also cruising and partial throttle inputs. On the ZX4 there is a lot of extra unnecessary fuel to limit the bikes performance. On the same front, better fuel economy can be retained.
• IGNITION - Optimized to make the most power while still being safe and reliable.
• THROTTLE DE-RESTRICTION - Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has a “dead spot” on the top end that kills the bikes power curve when it should be making the most . This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline.
• LOWER FAN-ON TEMP - Let’s face it, this bike rides a little on the hot side. To help not only the riders enjoyment but also keep the engine slightly cooler, we've lowered the fan-on temps.
• INCREASED RPM LIMITER (at customer request) - We can raise the factory limiter by 500 rpms safely at your request.
• INCREASED TOP SPEED LIMITER - Removed so you can let the bike run free in any track environment.
