My New to Me Monster 1100 Evo

Hi Mike

I kept the ABS as it works great and even after 34 years riding it can stop shorter than I can first time
in an emergency .

All M1100 evo have ABS.

the ABS will fit fine as it's all mounted on a sub assembly that fits between the mudguard and forks.

Good luck finding a set of Ohlins S forks as it took me 2 years to find a set (eBay.de)

your only problem will be finding 848 brake discs as the Ohlins forks have the calipers spaced 10mm
further apart.

I ended up fitting 330 mm 1098/1199 Discs as they are far more common on eBay.
