With 1" (25.4mm) riser clamp area. Gloss black powder coated and precision CNC machined from 7-grade billet aluminum. Rise is just 2" (5cm) for a compact; low slung set-up. The webbed one-piece top clamp connects both risers; assuring a stronger and more torque resistant connection from bar to bike than with individual top clamps. Especially beneficial with higher / wider handlebars. With the combination of style; strength and lightweight the Task Force risers come into the arena as hard hitters. Complete with stainless hardware. Note: With approval. Check your local MCS dealer or the MCS sales department for exact type of approval and validity on bike model and years on the test report.
