Hey everyone,
I recently tried swapping my stock master cylinder for a Brembo RCS Corsa Corta on my Yamaha R9.
The issue is that the stock brake lines don't seem to line up correctly with the Brembo banjo bolt orientation. Trying to fit them requires awkward routing and puts stress/kinks on the hard sections of the line, which doesn't feel safe at all.
For those who have done radial master cylinder upgrades on this bike or similar modern Yamahas:
Did you have to replace the front lines with custom/aftermarket braided lines (e.g., Spiegler, Core Moto, HEL)?

Is there a specific banjo bolt angle/adapter that makes the stock routing work without pinching the line?

Any advice or recommendations are greatly appreciated. Safety first!

Just picked up these two parts for my R9:

DNA Stage 2 air filter
SC-Project CRT full system

I am curious if anyone is already running this setup.

What tune are you using? Any noticeable difference in throttle response or power?

Also curious how the CRT sounds in person compared with the stock exhaust.

I will share the install and results once it is done.

Finally starting some upgrades on my Yamaha R9.

I just picked up a DNA Stage 2 air filter and an SC-Project CRT full system.

The goal is better airflow, sound, and overall performance while keeping the bike reliable for both street and track use.

Has anyone here tried this combination on the R9?

I would love to hear your experience, especially regarding:
- ECU tuning / remapping
- Throttle response
- Power gains
- Sound
- Any issues with the DNA Stage 2 filter

I will post some pictures once everything is installed.
Next step: getting the ECU properly tuned.
