Can't see why stainless bolts should be a problem?
They may not be as high tensile as the originals but, at the size they are I reckon they're well over any strength requirement and I can't imagine the temperature causing any issues? I've certainly used them without any bother.

The offset is the distance between a line drawn through the centres of the fork leg holes and the centre of the stem hole. In other words the fork legs will be 25mm in front of the steering stem (centres). The later SS has 30mm offset so can't be used with early Monster bottom yokes and indeed shouldn't even be used as a pair as the different offset will upset the geometry. Later Monsters were changed to 30mm offset with the introduction of the "ST" frame, whereupon they became interchangeable with SS yokes. I think I'm right in saying the early SS had 30mm offset too? No problem with stainless caliper halves bolts, but the kits usually have standard cap heads instead of the original low heads. Only trouble with stainless low heads is the increased likelihood of chewing the Allen socket out getting it up to the required torque. I had this problem with button head stainless disc bolts which had insufficient socket depth and would not take the correct torque. Best cure is to use steel or Titanium bolts. I always use Ti these days anyway, especially on un-sprung parts. RSR Moto are purveyors of fine Titanium bolts and also carbon fibre parts. They will be advertising on here in 2024.

I use ss yolks on my (94 framed) heap but also have clip ons and rearsets. I think Ducati went for the 25mm off set due to the upright sitting position on a Monster, as 851s (with the same frame) used 30mm offset.
Re stainless fixing, beware some are rubbish and rounding out socket heads can be an issue, also had bad experiences when used in Ali components suffering I think from electrolytic corrosion. Ti bolts (grade 5) are the job, but be warned Ti is addictive.

I'm wondering if I confused you with my SS abbreviation for stainless steel...

When I said ss yolks, I meant taken off a 900ss.

Great news about RSR Moto, I can vouch for the quality of their products and my (ex) bike is on their 'hall of fame' ;-)

I've just taken stock of some of their titanium front disc bolts which are great quality but I couldn't find any listed for the rear disc of the M900. They also didn't come with any washers so I'll have to check to see if they are required or not.

No washers required, as for the rear; M8 x 20 IIRC but I swapped mine for plated cap heads from 916 (M8 x 14) as they are a nice low profile and steel (need to be magnetic) due to using a speed sensor on them for the Translogic dash.

To add, these should be good; https://www.ebay.co.uk/itm/112686651...3ABFBM2pK5v8Bi
M8 x 20 but ignore that it says for 748/916 etc. as they only use 4 bolts and are shorter as the hub/carrier (not the wheel) they fit into is not very thick.

I recently bought a set myself. 12 for the front and 6 for the back.
He does do a rear set and a front set as it happens. All the same size on mine, M8 x 20. I like that they are the same pattern head as originals but sparklier. Flanged cap heads. I was so impressed with what a nice company it is to deal with that we got into a conversation and they agreed to put an ad on our forum banner.
