Today, I want to share my experience messing around with a Yamaha XJ6 and talking about its horsepower.

So, I got my hands on this Yamaha XJ6 a while back. It’s a naked bike, not too fancy, but pretty solid. The first thing I did was to take it out for a spin in the city. This thing zips through traffic like it’s nothing. The engine, a 600cc inline-four, feels really smooth. You twist the throttle, and it just goes.
I wanted to see what this bike could really do, so I took it to some open roads outside the city. Opened it up, and man, it’s got some kick. The specs say it’s got about 78 horsepower, and it definitely feels like it. It’s not the fastest bike out there, but for a 600cc, it’s more than enough for some fun.
Testing the Power
I did a few runs to see how it accelerates. Here’s what I did:
- Started from a standstill.
- Floored the throttle.
- Checked the time to reach 60 mph.
It wasn’t super scientific, but it gave me a good feel for the bike’s power. It gets up to speed pretty quickly, and the power delivery is smooth all the way up to 10,000 rpm. That’s where it hits its peak horsepower.
Engine Details
Here are a few details about the engine:

- Type: Four-stroke, transverse four-cylinder, DOHC, 4 valves per cylinder.
- Displacement: 600 cc.
- Cooling: Liquid-cooled.
This engine is actually a re-tuned version of the one in the FZ6, which itself is a re-tuned R6 engine. I heard from some folks that it rarely needs its oil topped up between services, which is a good sign.
Daily Riding
I used the bike for commuting for a week. It’s pretty comfortable for daily use. The seat height is 785 mm, which is good for me, and I heard it can be adjusted. It’s not too heavy, so maneuvering in traffic is easy. Plus, it’s decent on gas, around 43 mpg, and has a good tank range, about 200 miles.
Final Thoughts
So, after spending some time with the Yamaha XJ6, I’d say it’s a solid bike. It’s got enough power to be fun, but it’s also practical for everyday use. The engine is smooth, and it handles well in both city and open-road conditions.
If you’re looking for a mid-range naked bike that’s reliable and fun, the XJ6 is definitely worth checking out. It’s not the flashiest bike, but it gets the job done and puts a smile on your face.
