Okay, so I’ve been digging into the Suzuki Savage 650, also known as the LS650 or Boulevard S40. It’s a cool, classic-looking single-cylinder bike, and I wanted to get all the specs down in one place. Here’s what I’ve gathered so far, starting from the beginning of my search.

My Deep Dive into the Suzuki Savage 650 Specs
First thing, I started looking for general information. Just simple stuff, like what kind of engine it has and how big it is. I found out pretty quickly that it’s a 652cc, four-stroke, air-cooled engine. Single cylinder, like I said. That means it’s probably got some good low-end torque, making it a fun ride around town.
Then, I moved onto the more detailed specs. I wanted to know things like the bore and stroke, compression ratio, stuff like that. Here’s what I dug up:
- Engine: 652cc, 4-stroke, Air-cooled, SOHC
- Bore x Stroke: 94.0 mm x 94.0 mm (3.70 in x 3.70 in) – Yep, square engine!
- Compression Ratio: 8.5 : 1 – That’s pretty low, good for regular gas.
Next up, I looked into the transmission. It’s a 5-speed, which seems standard for this type of bike. I also checked out the final drive, and it’s belt-driven. Belts are nice because they’re generally lower maintenance than chains, and they run quieter, too.
I also gathered some info on the chassis and dimensions:
- Overall Length: Around 85.8 inches.
- Overall Width: About 28.5 inches.
- Overall Height: Roughly 45.3 inches
- Wheelbase: 58.3 inches or so.
- Dry Weight: About 353 lbs. Pretty light!
After that, I started figuring out more about the practical things, like fuel capacity and the electrical system.

- Fuel Tank Capacity: About 2.8 gallons.
- Starter: Electric.
It took me a while, I searched and compared different resources. It has a pretty simple, classic design. No fancy fuel injection here; it’s got a good old carburetor.
So, that’s my rundown of the Suzuki Savage 650 specs. It’s a basic, reliable, and fun-looking bike. Hope this is helpful for anyone else who’s curious about this machine!
