If you are in doubt of the security of the filter with just a half turn,put a gear clamp around it and safety wire it.I've done this with most of my bikes.Goldwing included.
Owner's manuals and factory service manuals have been known to contain errors.
If you have a spare filter lying around, can you measure the thread pitch and gasket thickness and post them here? I bet that would reveal the craziness of 2 full turns.
Uh, careful with specifying a general number like two turns, no force stated.
If you want to be specific, give torque specification.
The torque specification for the V-Strom 650 oil filter is 14.5 lbf-ft or 20 N*m
There are two reasons for the "2 turn" spec for the Suzuki oil filter:
1. The o-ring makes initial contact as a line (round o-ring to a flat surface) and needs some extra compression to make a secure seal. Most other filters use a ring with a flat face that has much greater initial contact.
2. The Suzuki filter uses a fine thread (M20x1) that needs more turns to compress the o-ring the same amount as most other filters (that use a 3/4-16 thread). One turn of the Suzuki filter advances the filter .0394 inches while one turn of a common filter advances .0625 inches. So you must turn the Suzuki filter 1.6 turns to equal the single turn that is usually specified for the normal coarse threaded filter (with the flat faced sealing ring).
Actually, one guy with a substantial mileage on his bike gave his honest experience, then a bunch of I-know-how-to doubt-you's flew in and wanted to know a pitch thread and I don't know what else ... typical GTAM cluster **** as far as technical advice is concerned here ...
Yeah. The PDF I have is the appendix or something of the service manual for the 2012. It is 21 N*m for the oil drain plug and says 20 for the filter.
Here is a copy of my document for you, might be useful for you to have on hand:

Well, since it's interesting to you, I'll chime in and side with V-Tom. Check the owners manual or tech manual and do what it tells you.Thread pitch and gasket thickness. Still waiting to find out the latter.
It's an interesting subject to me so I'm talking about it, and it's related to the topic. Do you have a problem with that?

For the record, the 2006 SV650/S owners manual also indicates two full turns after the gasket initially makes contact. Not surprising since it's the same basic motor as V-Tom's Stroms. Over 70,000kms and a dozen+ oil changes (using OEM filters) following the manuals' instructions, and no issues so far.
Regarding 2 full turns versus "hand tight" or 1/2 - 3/4 turn after seal contact ...
Any one of these may be correct for the OEM oil filter on your particular bike. It may not necessarily be correct for an aftermarket filter that uses a different type of sealing element. It may not necessarily be correct for other bike models.
Suzuki owners - do the aftermarket oil filters for your bike use a round-section O-ring, or a flat seal?
The bottom line is that what Suzuki tells you to do should be taken as gospel for the Suzuki but not for anything else, and what a different manufacturer tells you to do should be taken as gospel for that brand but not for Suzuki.
It's important to read what your owner's manual says about filters.
On the Suzuki V-Strom (and I suspect many of Suzuki's other bikes) the correct way to tighten the filter is to first moisten the o-ring with oil. Then gently turn it until the O-Ring on the filter touches. Then turn it two full turns.

Anyway, my point for the OP was to read what the Owner's Manual says for his bike, and even then it will only be completly meaningful when using OEM parts.
