timing chain 250 400 ?

[Mouser]

Hi guys,

Wanted to change the timing chain in my race fzr 400, the old one is getting to it's end...

Anyone tried already this "style" of timing chains?

http://www.aliexpress.com/item…R-250-RR ... 32744.html

The shape is different, seems to be lots of used now for lots of models, to they fit the cam's original sprockets?

This one is for the 250 fzr....is the width of the oem 250 the same than the 400? If yes, I could use the one for the 250fzr....the length is the same...112 links...if the width is the same, the strength should be the same too....?

thanks

Regards
