For those who like pictures....
Left -
120/100 - Kenda Trak Master II - DOT tire (I loved this tire on prior DRZ400)
Center is the stock 140/80 Pirelli MT-21 DOT tire (850-900 miles)
Right is Michelin M12 140/80 (stock size)
NOT DOT Do not plan on riding this on the road - it's super slippery. My plan is to re-install the worn MT-21 after the trails next weekend. Plenty of tread for road use.
Unmounted
Here is the MT-21 Stock tire still mounted. You can really see the height difference in sizes but also different manufacturers
ANGRY tire - Ready for some trails this weekend.
