Boom!

Hmm… that’s ridiculously cool. Holes everywhere dot com.
We’re using Works Expand (WORKS EXPAND) WRF022W to change from 240\u03c6 to 220\u03c6.<\/a><\/p>\n\n\n\n\n\n\n\n

The stock pads are worn down nicely, so safety first!
Don’t skimp on tires and brakes\u2014there’s nothing good about it (\u03a6\u03c9\u03a6)<\/p>\n\n\n\n

Wow!
That’s seriously cool…
Works Expand (WORKS EXPAND) WRF022W<\/a>

I’ve been wanting to try this out!<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It’s semi-floating, so it’s flexible in many ways.
Push and pull are definitely advantageous too (*’\u25bd’)<\/p>\n\n\n\n

When I compare them, I realize it’s quite a bit larger.<\/p>\n\n\n\n

The caliper support is the discontinued 69721-35F00.
We sourced it used and finished it with wet blasting (^_-)-\u2606<\/p>\n\n\n\n

We’ll machine the collar on a lathe with a +2\/100 press fit (‘\u03c9’)\u30ce<\/p>\n\n\n\n

Heat it up in the oven and it slides right in by hand. You want the press fit to go in smoothly.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Normally you need to mill the caliper mounting side a bit. It’s best to check the actual part before machining.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It’s less about customization and more about the importance of replacing critical wear items…
And it’s not about the exhaust, okay?<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This kind of parts-sharing trick used to be what made Suzuki great…<\/p>\n\n\n\n

Like the stock setup, it gets a rigid rod connection from the swingarm, so there’s no need to make the support floating.

<\/p>\n\n\n\n

When adapting parts, you need to know the pad contact width.

The hub wear is minimal…
