I have the adjustable levers on my 250.
different seller but same idea.
I bought the chrome ones (titanium color they said) with red adjusters.
Work perfect.

Have some on the GSXR too from China. No probs. Have had them over 6 months and do clutch wheelies and hard stoppies with them withotu worries.

Make sure the hardware is good on chinese levers and you'll be fine. Use locktite on the adjuster hinge bolts too. (not lever hinge bolts)

My bolt from the stock clutch lever perch also stripped out and stripped out the perch. A week and $30, new perch and bolt later I was able to install my $50 ebay levers. lol

No way can you go back to stock after using these. Definitely hands down better.
Ps I don't have the folding ones, just adjustables.
