Okay, so, I’ve been tinkering with my 2020 GSX-R 600 lately, and I thought I’d share my little adventure with you guys. The goal? Well, I just wanted to see how much power I could squeeze out of this bad boy.

First things first, I got the bike on the dyno. It’s a Dynojet 250i, to be precise. Right off the bat, it pushed out 102.9 hp at 13,520 rpm, and the torque was sitting at 44.0 lb.-ft. at 11,580 rpm. Not bad for a stock bike, huh?
Next, I slapped on a Power Commander. Now, from what I heard, this alone won’t usually bump up the peak horsepower. But, it does wonders for the throttle response and that mid-range power. After tuning it a bit, I could definitely feel the difference. The bike felt way snappier, especially when I was zipping around town.
But I didn’t stop there. I got my hands on a Race Tools package that included a Log Box D v3 and a Zeitronix ZT-3 Wideband O2 Sensor. This let me enable some cool features like a Quickshifter, Launch Control, and a Pit Speed Limiter. Pretty neat, right? With the Quickshifter, I was able to change gears without clutching, and it was smooth as butter. I usually shifted around 5,000 rpm to get the best mileage. If you are riding a 600cc, you might need to shift at slightly higher rpm.
- Dyno Test:
- Initial Run: 102.9 hp at 13,520 rpm, 44.0 lb.-ft. torque at 11,580 rpm
- Tuning with Power Commander
- Installed Race Tools:
- Enabled Quickshifter, Launch Control, Pit Speed Limiter
- I usually shift around 5,000 rpm or so on my 750, and maybe slightly higher on a 600.
What I Learned
Through this whole process, I realized a couple of things. One, these 600cc sportbikes are tuned for speed, and they’re quick. The GSX-R 600 has about 120 HP, which is a lot. Two, the peak horsepower is only available at very high RPMs. So, for everyday riding, you’re not always tapping into that full power. It’s the torque curve that gives you that usable power most of the time.
In the end, I didn’t really try to hit that max horsepower figure. I was more focused on getting the bike to perform better in real-world conditions. And I gotta say, I’m pretty happy with how it turned out. It’s a whole different beast now, and it’s even more fun to ride. So, if you’re thinking about tuning your GSX-R 600, I’d say go for it. Just remember, it’s not all about the numbers. It’s about how the bike feels when you’re out there on the road. And trust me, it feels pretty damn good.
