Sight Alloy 7.1 Demo Bike


View Sizing Chart



Delivering a perfectly balanced and incredibly efficient ride experience, the Sight Killer B is the complete package for all mountain riding. A short, ultra-stiff rear end, low BB and slack head angle speak to a ride that begs to be ridden as far and as fast as you dare. The Sight’s all mountain-tuned A.R.T. suspension system powers riders to the top of the steepest climbs and delivers grin-inducing playfulness and confidence-inspiring capability on the downs. For those who always take the lead in a pack, the Sight Killer B is the ultimate weapon.



  • ART Suspension
    Advanced Ride Technology, or A.R.T., is the direct link between engineering and experience. More than a single suspension platform, A.R.T. is a system that we optimize for each intended use. Norco’s engineering team strategically manipulates pivot locations to precision-tune suspension kinematics, ensuring that every full suspension bike will excel in the environment it was designed for. For downhill applications, we increase rearward axle path for a more controlled ride over gnarly, unpredictable terrain. For cross-country we increase pedaling efficiency and small bump compliance for a faster, smoother ride.

    A.R.T. delivers four major benefits to riders: enhanced pedaling efficiency, increased square-edge bump compliance, improved braking performance and progressive suspension characteristics. These benefits are balanced in different proportions based on intended use, creating a ride experience unique to each model.

    Enhanced Pedaling Efficiency
    A.R.T. is designed to effectively manage chain growth to create anti-squat forces that counteract the forces responsible for suspension bob. The result is an incredibly efficient pedaling platform, superior power transfer and unmatched climbing ability.

    Increased Square-Edge Bump Compliance
    Rearward axle path describes the rear wheel’s trajectory as a bicycle moves through its travel. A.R.T. uses a pronounced rearward axle path that enables the wheel to travel both rearward and upward, up and out of the way of obstacles.

    Improved Braking Performance
    A pronounced rearward axle path also allows a bike’s suspension to remain fully active when pressure is applied to the brakes. A.R.T. delivers powerful, predictable braking with fully active suspension and superior traction at all times.

    Progressive Suspension Characteristics
    A.R.T. suspension uses a progressive leverage ratio curve, meaning that the forces required to engage the shock increase progressively as the shock moves through its travel. The first part of the stroke is very supple and effectively absorbs small to medium-sized impacts. Toward the end of the stroke, the shock becomes progressively stiffer, resulting in a ‘bottomless’ feel. To the rider, this progressive curve is experienced as consistent, predictable suspension at every point in the travel.

  • Gravity Tune
    With traditional frame designs, engineers adjust front-centre lengths for each frame size but use a single, fixed rear-centre length. This approach leaves riders of certain body types in a poor position when standing. Poor body position leads to uneven weight distribution and negatively affects traction, control and overall performance and ride characteristics.

    A simple solution to a complex problem, Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimizing geometry for every bike in the line. As a result, weight is always optimally distributed – regardless of rider height. Available only on Norco Bikes, Gravity Tune means equal ride characteristics and unrivalled control for all.

  • Size Scaled Tubing
    By increasing tube profile dimensions in proportion with frame size, Norco engineers are able to calibrate frame stiffness to the weight of the prospective rider. This ensures that a heavier rider on an extra large frame will experience the same ride characteristics as a lighter rider on a small frame. Though the process is labour-intensive, the result is worth the effort: optimal ride characteristics, performance and comfort for riders of all sizes.
