I need a new M/C. Stock is 17mm, but it seems everyone is selling 19mm. I'll get a firmer pedal and less stroke with the 19mm, correct? Is this good or bad or personal preference?
What are the advantages/disadvantages of both? Thanks! -Jeff ----------- |

IMHO, I try to avoid locking up the brakes. You can get bigger and/or softer tires. Hard stops aren't my thing but it is nice to know you can stop quickly. Are you sure your brakes are bedded in? You can do the bedding in process again if in doubt. (IMG:style_emoticons/default/beerchug.gif)

When I tried swapping in some Textar pads, I could not lock up any wheel. |
