How To Choose Motorcycle Brake And Clutch Levers

A lever set changes three things: how far the rider has to stretch to reach the blade, how much effort it takes to pull it, and what happens to the lever in a fall. Everything else is styling.

Reach is set by the adjuster wheel. A six position adjuster covers almost every hand size, which is why an adjustable aftermarket lever is a genuine upgrade on a bike that came with a fixed OEM lever. Effort is set by the pivot geometry. A save-labour pattern uses a longer effective arm so the same hand force produces more pressure at the master cylinder, which matters most on heavy clutch cables and older hydraulic systems.

Four profiles cover almost all demand.

• Regular length is the default. It replaces the OEM lever one for one and is the volume seller.
• 3D short levers are cut back so only two fingers reach them. Track riders like them because there is less to catch in a fall and less to hit the bar.
• 3D long levers keep full four finger coverage with a machined profile. Popular on touring and naked bikes.
• Folding levers are hinged at the mid point. In a drop the blade pivots outward instead of snapping. They cost more and they save a master cylinder.
• Blade levers are a slim, flat profile bought mainly for looks, and they suit a build where the whole cockpit is being changed at once.

Aftermarket levers in this class are CNC machined from aluminium alloy and anodised. The alloy grade matters: T6 tempered aluminium is noted on some patterns and is the specification worth asking about, because a soft alloy lever will bend where a T6 lever will hold.

Anodising is a surface treatment, not a paint layer, so the colour will not chip off the edge. It will fade over years of UV exposure, more visibly on red and blue than on black. If you are merchandising a colour wall, order the colours you actually sell in depth rather than one of each.

Levers are sold on a universal fitment pattern covering Aprilia, Benelli, BMW, Buell, Bimota, Ducati, Honda, Kawasaki, Yamaha, Suzuki, Hyosung, Moto Guzzi, Triumph, KTM, Can-am, Husqvarna, MV, Bajaj and Vespa. Universal here means one pattern covers a large group of models, not that one pattern covers everything ever built.

Before a first order, send the exact model and year list you intend to serve. Fitment mistakes are the single largest source of returns on this product line, and they are entirely avoidable at the quotation stage.

• Alloy grade and whether the pattern is T6
• Number of adjuster positions
• Which colours the anodiser can hold consistently across repeat orders
• Whether the price is per pair or per piece
• Whether laser marking on the blade is possible for your brand
• Packing: retail blister, polybag, or plain export carton
