One problem is that there are a lot of uncovered plastic edges on this protector-some a bit sharp. They poke and wouldn't offer the best protection in a crash. There are a lot of areas left exposed to roost, especially around the sides of your chest. And there isn't much covering the lower back. Acerbis used to make a similar protector called the Proton that was much more simple yet covered a lot more. As you can imagine, the Impact isn't as happy under a jersey. If I were going to take the time to put on a chest protector, I'd choose one that protected me a bit more. -Jimmy Lewis

8OO/659-144O; www.acerbis.comScotts Performance productsBillet Shark FinMost stock rear disc rotor protection is plastic at best and stands little chance of defending your brake from rocks. I've actually broken the tabs off my Honda XR400R's swingarm with a bolt-on shark fin; and when I finally snapped my caliper carrier (don't ask, it involves sliding backward down a hill!), I needed a fix. This $129.95 Scotts billet unit integrates the carrier and shark fin into one strong piece that's so cool looking I hated to put it where it would only be abused. It was simple to replace the caliper pins and reinstall the caliper. On the XR400R the axle is completely enclosed as opposed to the half-circle coverage of the stock carrier. This won't matter as I usually remove the axle from the wheel during tire changes anyway. I'm happy to report that this shark fin has hit plenty of rocks and is still straight and hasn't let the disc take any damage. -Jimmy Lewis

818/248-6747; www.scottsperformance.com1X InternationalChain BreakerA chain breaker can be the make-or-break tool on a ride. The 1X International version is machined from hardened steel and doesn't take up much room. Activated with a 10mm wrench or socket, it has helped us break top-line O-ring chains with ease, no grinding necessary. It takes only minutes to use and fits easily in a fanny pack; our biggest concern is losing it. It's only $19.99 but may be worth 10 times that when you really need it. -Jimmy Lewis
