★★★★☆
The Terra Force-MX SM is built for motocross racers who live on soft ground — exceptional track grip, but not a street or hard-pack tire.

Best For
Soft-Terrain MX Racer
You're lining up on sand, loam, or freshly worked tracks where traction makes or breaks your moto. The Terra Force-MX SM hooks up fast off the gate and keeps digging as the track gets chewed up — exactly what this tire is built to do.
Perfect Match
Weekend Warrior Motocrosser
You hit local tracks on weekends and want race-quality grip without swapping rubber after every session. Mitas optimized the compound to hold up across multiple outings, so you get serious performance without burning through your tire budget.
Great Match
Hard-Pack Track Rider
If your home track runs blue-groove, hardpan, or dry-pack conditions, the SM's soft compound and knob spacing won't be in their element. The Terra Force-MX MH is the right call — built specifically for firmer surfaces where a harder compound and tighter tread deliver better traction and tire life.

Frequently Asked
This tire was developed for soft to medium terrain — think sand, loam, and freshly tilled tracks. The deep knobs are spaced to penetrate loose surfaces and shed buildup, so traction stays strong through acceleration, braking, and cornering. It's not the right call for hard-pack or blue-groove conditions.
Yes. The Terra Force-MX SM is specifically optimized for mousse compatibility, so the internal geometry accommodates foam inserts without fighting the fitment. It's a clean setup for racers who want to eliminate pinch-flat risk entirely.
Mitas engineered the compound to balance outright grip with usable durability — it holds up across multiple motos or sessions better than many comparable soft-terrain race tires. That said, longevity depends on how aggressive your riding style is and how rough the track gets. Expect strong performance, not indefinite mileage.
The Terra Force-MX SM covers the full youth racing range, including 60/100-12 and 70/100-10 fronts and 80/100-12 and 70/100-10 rears — enough to fit most 50cc through 85cc machines. If you're not sure what your bike takes, call us at (714) 516-9059 and we'll sort it out.
No — and we'd rather be straight with you than have you buy the wrong tire. The SM is purpose-built for soft terrain. For hard-pack or firm-base conditions, the Mitas Terra Force-MX MH is the variant you want, with a compound and tread pattern dialed in for those surfaces.
The colored stripes are Mitas' quick-ID system for distinguishing the SM (soft-to-medium) variant from other Terra Force-MX models. In a busy pit area where tires can look identical at a glance, it's a practical detail that saves confusion when you're prepping between motos.
