papac2000 Posted January 20, 2015 Share Posted January 20, 2015 Does the Yamaha manual actually recommend keeping below 4500RPM for a specified period? I have been on several bike forums over the last couple years and there has been lively debate about "hard break-in" versus "soft break-in". While I don't believe flogging a bike the first hour it runs is ideal, today's modern engines have extremely precise finishes in the bore (in fact our engines are a spray-in linerless type....mirror finish!) and require much less break in than traditional cast liners might. I inquired with my dealer and he said after a few heating and cooling cycles you are good to go. I just was curious as to the manuals actual recommendation/requirement. I plan on riding mine on the dyno for a while to simulate a short break-in before testing the 3 throttle modes to compare output. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...
