# What the MS2.1 is and who it's for Speed MS2.1 is a 1/10-scale, 4WD touring car kit released as the next step after the MS2.0. It's aimed at racers and experienced hobbyists who want a buildable platform with multiple material choices and several small but targeted updates intended to improve lap pace and component durability.
# Notable mechanical updates
- Chassis options: graphite, aluminum, and steel versions will be available, letting builders select stiffness and weight distribution that fit their setup strategy.
- Front suspension: graphite front suspension arms are 1 mm longer to alter geometry for a more aggressive driving style. Front suspension lever ratio is selectable to tune behavior for track conditions and tires.
- Shock and mounting changes: a graphite front shock tower and new shock mounting hardware (including an aluminum front lower shock mount and aluminum rear upper shock mount) shift the shock mounting angles and lower center of gravity.
- Stabilizer and motor changes: a front stabilizer wire is included, and an aluminum motor mount replaces prior parts. Layshaft and motor-mount tolerances were updated to reduce spur-gear failures.
- Hardware updates: screws used with the 1.5 mm aluminum and 1.2 mm steel chassis now feature a larger 2 mm hex head. The steel chassis itself was revised to a next-generation design.
# Why these changes matter on track
# Options, conversions, and setup flexibility Yokomo is releasing the MS2.1 with three chassis material options—graphite, aluminum, and steel—so drivers can choose stiffness and mass distribution that match the track surface and driving style. A conversion kit will be available for MS2.0 owners, allowing teams who already own the previous platform to upgrade key parts without buying a full new kit.
# Where to find official details and coverage The initial announcement and product gallery were posted by Big Squid RC on September 17, 2026, with product details and links to Team Yokomo's official pages. Additional coverage and deeper spec breakdowns are appearing on RC-focused outlets that received the same release information.
# Practical next steps for interested buyers If you're deciding whether to buy or upgrade, compare the three chassis materials against your typical track (high-grip carpet vs low-grip epoxy, for example) and check whether the conversion kit covers the specific MS2.0 parts you rely on. Expect to adjust shock angle and front lever ratio as part of setup work when switching to the MS2.1 configuration.
