For you peeps with the service manual, what are the valve diameter, intake cam and compression specs for the new Wee? Like IN 31mm EX 25.5mm, Cam height 36.38-36.425 mm, and standard compression pressure 185-242 psi. These are the specs for the Gladius.


Thanks in advance!

These are the engine specs listed in my manual. Bore: 81mm, Stroke: 62.6mm , Compression Ratio: 11.2:1, Displacement: 645cm^3. As far as the compression psi that isn't listed in my manual.

Thanks

Another Dave T! :mrgreen:

Anyway, that must be the information from the owners manual. The Gladius has the same bore and stroke but it has a 11.5 to 1 compression ratio. So the pistons must be different.

The dealer told me the Gladius and the strom have the same engines now. If that's true I don't really understand why they aren't selling the Gladius in the US.

The cams and compression ratio are milder on the Strom. The pistons are different, as are some other parts. It's based on, not same as.

Nothing to do with the engine. Marketing determined that the Gladius styling was, ummm, a little too polarizing for the US market. (The words on the street were not quite as polite, I gather).

Thanks Greywolf.

They said the cylinders are different also from the Gladius, I wonder how? :confused: Plated versus iron sleeve?

Gladius EX cam height: 35.68-35.725mm

Boy, that exhaust cam is a lot lower...

Who are they? The 2009 Gladius and 2012 DL650 have the same cylinder part numbers, 11211-44H00-0F0 front and 11221-44H00-0F0 rear. The Gladius is designed for power and the Strom for tractability.

The con rods are the same, piston dif, crankshaft dif, valves same, valve springs same, camshafts dif.

This one, unless I'm reading it wrong and they are comparing it to the SV instead...

2012 Suzuki V-Strom ABS & ABS Adventure | RoadRUNNER Motorcycle Touring & Travel Magazine

Piston for Gladius: 12111-44H00-0F0

Piston for 2012: 12111-44H10-0F0

Crank for 2012: 12220-44H10

Crank for Gladius: 12220-44H00

What is the diameter of the throttle bodies? Gladius has 39mm...

If the throttle bodies are much smaller it would probably be better just to get a whole Gladius motor...

The "same engine as Suzuki's Gladius" is wrong to start with, as was "the original V-Strom 650 used the SV650’s engine". Based on would be more like it. I'd infer the implied comparison between parts is to previous DL650s. The 2004 DL650 had 39mm throttle bodies. I didn't find a throttle body size on the 2012 but I suspect it is still 39mm.

K3 SV650 cam specs:

IN 36.06 mm to 36.105 mm 31mm diameter
EX 34.68 mm to 34.725 mm 25.5 mm diameter

Cylinder bore: 81 mm and 11.5 to 1 compression ratio

Just making notes. Blair has some SV cams for $120 thinking about purchasing...

Don't sugar-coat it. It's been labeled a chick bike. That is the word on the street!
