And of course, none of the tire changes or other work I’ve done on the RC390 would be possible without a rearstand, which means installing swingarm spools. The thing is, most spools are secured with steel bolts, and some RC390 riders have discovered that in a crash a spool may get torn off—and the steel bolt may take a part of the swingarm with it! Frank’s spools are machined entirely from aluminum and they’re designed to sheer off in the event of a crash, thereby protecting the swingarm from damage. I haven’t tested that theory, but I have used the spools to lift the bike up on a stand for tire changes, oil changes, and other maintenance. The spools are $45 a set and they come in silver or black.
