I recently installed the ZARD "Bad Child" Full Kit & Slip-On Exhaust on my 2017 BMW R Nine T ABS, and it’s a total game changer. From the moment I fired up the bike, I could tell this was the upgrade I had been searching for.

The design of the "Bad Child" system is stunning. The aggressive, race-inspired look of the full kit fits the R Nine T perfectly, giving it a more muscular and custom feel. The finish is immaculate, and it really brings out the bike's bold, modern classic vibe.

The sound is exactly what you’d expect from a high-performance exhaust—deep, throaty, and aggressive. The growl at idle is incredible, and when you open the throttle, it lets out a roar that demands attention. It’s loud, but not obnoxious, giving you the perfect balance of excitement without ruining the riding experience.

Performance has been noticeably improved. Throttle response is much sharper, and the bike feels more responsive and eager to accelerate. The slip-on paired with the full kit has made the R Nine T feel even more agile and powerful, and I’m looking forward to taking it for some longer rides to feel the full benefits.

Installation was seamless—everything fit perfectly and the process was quick and easy. ZARD really knows how to create systems that not only look great but also deliver top-tier performance.

If you own a BMW R Nine T and want to unlock a deeper, more aggressive sound and boost your bike’s performance, I highly recommend the ZARD "Bad Child" Full Kit & Slip-On Exhaust. It’s the perfect upgrade for anyone wanting to give their bike a more exciting, commanding presence.
