Clicked 2 times in the last monthBPA-RACINGBPA-RACING Motorcycle Chain Slack Adjuster Tool - Innovative Chain Tensioning Tool for Easy, Quick & Precise Chain Slack Adjustment- Slack Setter Tool (Red)
Main highlights- THE SOLUTION FOR PERFECTLY ADJUSTED CHAIN 24/7 [PATENT PENDING]: Once this dynamic comparator is calibrated for your motorcycle, it indicates in real time what the perfect slack of the chain should be. The easy to read indicators will let you know if the chain is too loose, OK or too tight.
- THE #1 TOOL OF THE MARKET - “the best or nothing”: Your safety, comfort and taking the best care of your precious motorcycle could really depend on something so simple like your chain’s slack. And this innovative, one of its kind, buy-once, use-for-a-lifetime BPA chain adjuster tool, can really make all the difference. One unbreakable tool for an always precise chain slack. Sounds like a fair deal!
- PERFECT FOR ANY MOTORCYCLE: Thoroughly designed for 3.5 years, the BPA-Racing Slack Setter Tool grants an easier, quicker and more precise adjustment of the slack for all types of motorcycles – Standard, Café Racer, Scrambler, Sport Bike, Sport Touring, Cruiser, Adventure, Enduro and Dual-Sport.
- NO MORE COMPLICATED MEASUREMENTS: If you have ever tried to adjust the tension of the chain manually, with all the measurements and readjustments the service handbooks suggest, you probably know how hard that can be! This tool is made for the comfort of the rider! Very precise chain adjustment in just two minutes, without even requiring all those repetitive, time consuming and complicated measurements with tape. You don't even get your hands dirty.
- CHAIN TENSION MATTERS - SAFETY COMES FIRST: Incorrect chain tension can damage various components of your motorcycle and result in accidents. If the chain is tensioned too much, it causes wear on the sprockets while it prevents rear suspension from working properly. If the chain is too loose, it rattles and could jump off anytime. In both cases, dangerous accidents could be caused. With this innovative slack setter you can safely enjoy all your rides to the maximum!
