Viper 3121V Powersports alarm system

Keep your gear secure and your mind at ease

Viper designed and engineered their 3121V security system specifically for motorcycles, ATVs, boats, personal watercrafts, and snowmobiles. This alarm system features two 2-button waterproof remotes, a compact, waterproof alarm module, and a miniature water-resistant siren. The alarm also features a closed loop trigger, which is great for protecting helmets, saddlebags, and other valuables. You snake the trigger wire through your item, and if the wire gets broken, the alarm sounds.

There's more

Using the adjustable onboard shock and tilt sensor, the system will warn off most would-be thieves messing with your vehicle. An extra trigger input and an auxiliary output give this alarm system the versatility to work for you in almost any configuration, including controlling cabin door locks and lighting. If someone tries to steal a motorcycle armed with a 3121V, the anti-jacking mode will activate the siren, flash the parking lights, and disable the engine.
