Riot MKIII: 31.8mm handlebar clamp

The Riot MKIII Direct Mount Stem uses a 31.8mm clamp and CNC-machined billet aluminum construction. Black and chrome finishes are listed; check the selected finish’s availability on the product page.

Check the mounting arrangement

Identify whether your bike is a Pro 1.0 or 2.0 and check any fork or crown changes. The MKIII product describes E-Ride Pro applications broadly; confirm the mounting pattern on your exact setup. This category does not establish 3.0 or SR fitment. The 31.8mm bar measurement is only one part of that check.

Compare handlebar clamp sizes, widths and rise options when planning the cockpit. Confirm clearance for controls, cables and brake hoses before changing the bar position.

Contact Riot Racing with your bike year, fork model and bar diameter for help confirming the stem and required hardware.
