Decisions, I'm upgrading to a 103 next, do I do the 555s at the same time?

 

I like to space out my performance mods, keeps me from getting bored of the bike. Run it with the 255s, then swap over to the 555s if the thrill of the 103 starts to ebb...

If you do keep the 255s when you do the 103 you'll want to install compression releases.
