Looking good mate. Did you torque those Ti bolts up properly? Only asking cause I bought some marchesinis with Ti bolts that had been over tightened and I had to drill 3 out because they stripped the heads

Ti bolts can be a pain if not put in properly

Done them up hand tight can get the garage to check them when they go in for the tyres getting put on

Have you got the torque setting for our bike Kyle ?

I've got the torque value for standard bolts but not Ti
You should be ok as long as your not over tightening

I'm not a fan of loctite but if you are using it use the blue loctite not red.
Red had been used on mine which was part of the problem

Torque settings should be in the service manual downloadable from the 4c8 section , if not the give me your email and I'll see if I get chance to email it to you

Not using loctite Damo said not to I'm not a great fan either I've got them tight then just gave them a little bit more from that

That will be for standard bolts will it not?
Ti bolts may be different I'm not sure

Sorry jompy didn't even see you had posted up there is there much fluctuation with torque setting with ti over stock ?

Benji just had a look in my little book of knowledge and here's some info, I must stress this is not directly referring to disc bolts but titanium bolts in general.

Basically anything that gets hot and then cold again (which your discs do) when using titanium you should use anti-sieze compound and increase the torque value by around 10%

The torque setting for original bolts on your 4C8 is 18Nm

So using that here's what I would do if I was using Ti bolts I would put a small dab of anti-sieze compound on the thread and torque them up to 21Nm and you'll be good to go



If you don't have a torque wrench just a good tight nip will do

Ok I'll grab some anti sieze compound before they go on the bike always get worried with them snapping when getting them tight or stripping them lol

what Kyle said . . . . . i think

When i spoke to ProBolt they said about 30 % less torque which seems odd to me and not correct,anyway i just did it the ole fashioned way of 'feel' then a little nip up,always worked for me as going off Yamaha's torque settings can result in a snapped bolt.....eh Pod

30% less????
Jesus no way would I trust that. My info just relates to titanium bolts in general not bike disc bolts but no way would I be going 30% less. That makes it 12Nm almost finger right

Well the old fashion way it is then then check after the first ride out
