I recently bought a used 2015 S40 which has some bolts oxidized and some rusted. The bike was parked outside/outdoors for some time I believe.  
Is there an easy way to order many of bolts which can be replaced on the bike?  or even a list of them based on the section of the bike.  Thanks.

I have replaced many of the bolts on my 2014 with SS socket head bolts.
I did it a few at a time. Much nicer, no more rust. The bolts are widely available at hardware stores.

While that may seem like a good idea - you will find that stock replacement hardware is pretty expensive.

Also the current Covid affair is making it very difficult to get any OEM parts online.  The online dealers don't stock Suzuki parts - they order parts from their supplier and send them to you.  Earlier this year I tried to order the plastic stone guards that are on top of the forks.  My forks were apart and waiting for them to arrive.  After 2 months of waiting I was lucky that our member Ruttly had some and I bought them from him and cancelled my online order.

On November 3rd I ordered a few Suzuki bolts and a couple oil seals for the compression release shaft on the Suzuki Savage.   Every few days I get an email from the seller telling me that there has been a delay and the parts have not yet shipped.

If/when you go online and the parts list shows the in stock - that doesn't really mean the seller has it sitting on a shelf waiting for you to buy it from them.......I believe it only means that the part is available from the supplier.

So - my suggestion is that you buy replacement nuts/bolts from you local hardware store when they are available - and only order them from Suzuki when they are specific bolts/nuts for a special application.

I bought this stainless engine bolt set off eBay, and it is nice and works great.  When you install the engine bolts - be very careful not to over tighten them.  The aluminum threads in the engine block are easily stripped if you apply too much torque.  Use a small torque wrench that measures in inch pounds.....don't attempt to use a 150 ft/lb torque wrench set to a low setting - as they just aren't accurate at those low settings.  (If you don't have a torque wrench use one hand on a 3/8" ratchet with the palm of your hand near the head of the ratchet).    

Also know that stainless steel fasteners are more brittle than what you currently have on your bike. For that reason they shouldn’t be used to support a heavy load in sheer. The engine/frame through bolts come to mind.

I would definitely change the head to header bolts with studs and dome nuts
rusty or not.

I buy bolts from Longview bolt and screw.
Hardware stores are expensive.
Someone Sells to the hardware stores
That's where I go

in tension or torque?

Our bolt fail when being torqued so it's a different issue... usually.
