VRWEARE Universal 7/8″ Brake Pump With Mirror Hole
Best for riders who want a universal 7/8″ handlebar brake master with an integrated rear-view mirror hole. The product lists a 12.7mm piston bore and a 10×1.25mm banjo bolt, which supports common hydraulic setups. This lever is well-suited for dirt, pit, ATV, or scooter builds that require a straightforward hydraulic master cylinder without specialized mounting adapters. Limitation: data does not confirm compatibility with all ABS-equipped systems, so verify fitment with your bike’s brake line configuration.
WEIYINGSI Left Hydraulic Brake Clutch Master Cylinder Lever
Best for riders seeking a dual-function lever suitable for hydraulic brakes and clutches on 7/8″ handlebars. It supports an 8mm banjo and fits 90cc, 110cc, and 125cc bikes, making it a strong option for smaller displacement motorcycles and pit bikes. If your setup uses a separate brake switch, this lever accommodates that feature. Limitation: some builds may require adapters for non-standard mounting positions or remote reservoirs.
Feiteplus CNC Hydraulic Master Cylinder Reservoir Lever
Best for riders wanting an adjustable hydraulic master cylinder with CNC craftsmanship and a compact reservoir design. Compatible with standard 7/8″ handlebars, it provides precise lever feel thanks to adjustable components. Selecting this option can benefit riders who value fine-tuning braking response for track days or spirited street riding. Limitation: the listing does not specify a full feature set like mirror holes or integrated switches, so verify compatibility with your specific controls.
7/8″ Hydraulic Master Cylinder With Reservoir
Best for sport, street, and dirt bikes with 7/8″ handlebars seeking a comprehensive hydraulic system including a reservoir. The product covers popular brands across Honda, Kawasaki, Suzuki, Yamaha, and more, noting compatibility with cable clutch levers as well. Limitation: actual lever feel or pedal throw is not described in the listing, so potential buyers should confirm travel and mounting tolerance on their bike.
7/8″ Left Hydraulic Brake Master Cylinder For ATV/Dirt Bike
Best for universal ATV and dirt bike use with a 50cc-250cc engine range. This master cylinder is positioned as an all-around option for GY6 engines, quads, mopeds, and dirt bikes, offering a broad fitment. Limitation: the listing does not clearly state whether mirror holes or brake switch compatibility are included, so verify those features if you depend on them.
Buying Guide: Key Purchase Considerations
- Handlebar fitment: Ensure the lever and master cylinder fit standard 7/8″ (22mm) handlebars common on most motorcycles, dirt bikes, and ATVs.
- System type: Decide between hydraulic brakes (typically better feel and modulation) and cable/clutch combinations based on existing components.
- Mounting features: Look for banjo bolt size, presence of brake switches, and compatibility with rear-view mirrors if needed for street use.
- Adjustability: Consider adjustability in lever reach and backlash to tailor braking response to your riding style.
- Durability and materials: CNC-machined parts and rugged reservoirs generally offer longer life and consistent performance under varying temperatures.
- Compatibility notes: Some listings omit explicit compatibility with ABS, remote reservoirs, or specific brake lines—verify before purchasing.
