I'm looking at ways to slightly reduce the seat height of my Ninja 250R, so I can teach my older kids to ride. There's a company that makes these blocks that supposedly raise the handlebars and lower the front-end of the bike. Are these just blocks of aluminum with unthreaded holes in them? If so, I'd be willing to make a batch of them (CNC machined billet, w/ stainless or Ti fasteners) if anyone else wanted some. If it's more complex, I'll probably just buy what's out there. $60 just seems kinda high, though, for a couple pieces of easily machined billet (and longer steel bolts, I assume). edit: nevermind, this was addressed in another topic. Thanks verm!
