grunthorpe Posted January 5, 2015 Share Posted January 5, 2015 Hey Guys,I have a new KTM RC125 on order (as you may have heard me bragging in another thread )I just wanted to know the general opinion of you guys about the running in period, the manual recommends not exceeding 7,500rpm or full opening of the throttle within the first 600 miles or so. Do you consider this an essential part of the new bike process, obviously I don't want to damage my bike and will be patient if necessary.As you can imagine, I am pretty keen to use the full potential of my bike ASAP, especially as it's only a 125 Thanks,Nick Quote Link to comment Share on other sites More sharing options...
Guest Posted January 5, 2015 Share Posted January 5, 2015 Suzuki recommends valve clearance checks every 7.5k for a bandit 2005...My mate just passed 21k and whilst riding with me on Sunday, putting his RPM's right up there, the engine block cracked and is now a non-runner. My bet is that's due to too low clearance on the valves (which have never been checked), built up too much pressure in the engine and boom!.Perhaps you should go with what the manufacturer suggest if you want your bike to last Quote Link to comment Share on other sites More sharing options...
Glorian Posted January 5, 2015 Share Posted January 5, 2015 Go with what the manufacturer says. Once spring is here 600 miles is a quick ride anyhow Quote Link to comment Share on other sites More sharing options...
fq-craigus Posted January 5, 2015 Share Posted January 5, 2015 Yes its important for all surfaces to mate together properly, labouring up hills is great for running in rather than nipping round town. 600 miles i would do that in a weekend if the weather wernt too bad, you will be surprised how quick it goes.

Fozzie Posted January 5, 2015 Share Posted January 5, 2015 You get people always spouting it's not important any more.The correction is, it is still important, just not as delicate as it once was. As in, when the engine is warm and has done a few hundred miles you can probably get away with a few stints at high RPMs. A manufacturer advises it for a reason, do it, stick to their schedules as it was designed to last under those parameters. Doing different because you believe otherwise is basically inviting problems for no good reason Quote Link to comment Share on other sites More sharing options...
Guest Posted January 5, 2015 Share Posted January 5, 2015 lets be clear. you're asking a load of strangers if its OK to ignore the advice of the people who actually designed your bike. people who have a vested interest in the models success.If someone says.. go for it. redline it everywhere from mile 1. do you think they'll do anything for you if the bike went horribly wrong and you were left with a broken machine and a warranty that was declared void?I doubt it.'bad luck mate' isn't much compensation set against (UK price) £4,499 thats disappeared down a black hole.

Chrissb6 Posted January 5, 2015 Share Posted January 5, 2015 There's not just the engine to consider, the gearbox, brakes, forks, springs, tyres and numerous bushes through out the bike all have to be bedded in before you go looking for the red line Quote Link to comment Share on other sites More sharing options...
Joeman Posted January 5, 2015 Share Posted January 5, 2015 Put your foil hats on lads, here comes the conspiracy theories!!Its all health and safety rubbish. they are covering themselves as you're on a new bike that you're not familiar with so they explicitly tell you to ride it slowly...Also, it means that the bike gets older, and so further through its warranty period before its thrashed, leaving less time for the bike to break under warranty...

grunthorpe Posted January 5, 2015 Author Share Posted January 5, 2015 Well, it's clearly a unanimous decision! Thanks guys, just wondered if it was just KTM ass covering that's all good complete answers fellas Quote Link to comment Share on other sites More sharing options...

They get round that now, when I last bought a new bike, the guy walked me around the bike and made sure when I signed for it they made sure I was accepting I'd been walked around the bike and told to be careful, and of the run in procedure.And the latter they've got round by recording the bikes rpm history. If you did 14,000rpm 2 minutes after switching it on and you're claiming they owe you a new head, they can tell you to get your wallet out You can throw that at the conspiracy theorists next time! If a manufacturer wants to get away with those things, they make you aware of efforts they've taken to make sure you can't take the piss. None of this cloak and dagger stuff conspiracy junkies love Quote Link to comment Share on other sites More sharing options...

Stu Posted January 5, 2015 Share Posted January 5, 2015 heat has nothing to do with it directly valve seats burn due to the valve not been closes and sealing thus enabling the combustion of the fuel burn the valve seat this will not make the bike run hotter or overheat it could be a number of things that has caused a cracked head Quote Link to comment Share on other sites More sharing options...
Tango Posted January 5, 2015 Share Posted January 5, 2015 Run it in according to the book mate......not a great hardship for the few days/week it would take...... Quote Link to comment Share on other sites More sharing options...
Fozzie Posted January 6, 2015 Share Posted January 6, 2015 it could be a number of things that has caused a cracked head On a 2005 bandit, it only has a oil cooler and an air cooled head. With bad service history, it was probably low or old and not removing heat properly... Give it a good ride with some high rpms, head heats, gasket blows, sudden pressure leak and temp change causes massive thermal stress and *CRACK* Quote Link to comment Share on other sites More sharing options...
soll Posted January 6, 2015 Share Posted January 6, 2015 got my bike in november 2014, due to illness and cold weather i have only racked up 300 miles, so i still have to rn mine in for a few more.even so my trips are mainly short and no more than 50-60 mph limits. can do 50 on mine in 5th at 6 krpm.will soon rack up the miles when the weather sorts its self and i can get rid of this lurgy.... got my challenge 100 tags to get Quote Link to comment Share on other sites More sharing options...
