What is the compression ratio of a drz-400e and drz-400s? On suzukicycles, the said that the compression of the z-400 is 11.3:1. It is the same of drz-400s? And by the way, whait is the power of both bicyles?

 

hey the drz 400s is the same compression as the z400. 11:3:1.....and for thedr-z400e the compression ratio is 12:2:1....i am not sure of the power at all...sorry

 

According to dirtwheelsmag.com, the bike comes with a 12.2:1 compression ratio, just like the DRZ-400E. Here is the quote:

"Powering the Z400 is a high-performance 398cc liquid-cooled, DOHC, single-cylinder four-stroke engine. It features four valves and a high 12.2:1 compression ratio (the dirt bike engine has a 11.3:1 compression ratio). The bore and stroke is 90x62.6mm which is exactly the same as that on the dirt bike engine. Fuel is supplied by a 36mm Mikuni carburetor which is also the same as the DRZ. A dry sump lubrication system helps to create a more compact engine package."

I have a deposit on a Z400 at my local shop... they called and said they should take delivery of the first couple bikes in the next few weeks. I can't wait!

Go to the Suzuki America web site, the only differences I can see between the two are Z-400 11.3:1 36mm carb, DRZ-400 12.2:1 39 mm carb
