View Full Version : Fitting clip-on bars?

Quick question...I've been looking for some clipon bars.
The factory hyosung ones are more expensive than aftermarket ones (and probably weaker materials too), so I need to find something else that will fit.

The hyo has 51mm fork diameter, but clipons seem to come as either 50mm or 52mm sizes.

Do you buy the smaller size and squeeze it on, or can the bigger size be over-clamped?

I've been to a bike shop and they weren't sure...they even suggested it might be that they are designed to be stretched out first and clamped on...and you might need a 48mm size etc...

There's been a couple of 50mm sized ones on trademem lately, but I need to know what will work before buying

Get the 50 and take to local engineering shop to machine out to 51.

Or just get standards

And unlike a rudy bit they do not 'stretch' to accommodate all sizes!

A 51mm fork takes a 51mm clip on. Tight is best - so tight you may even need a bit of lube to slide it in there, oops on there.

What you could do is get a strip of .5mm shim stock and cut a strip to insert under the bigger clipons. It must be same width as the clipon and go everywhere the metal on the clipon goes.Id use bronze rather than steel shim.

I found (to my detriment) that you have to be just about millimetre-perfect with clip-ons. I've got 33mm forks, 32mm were too small. Could not get them on whatsoever. I ended up grinding out the insides myself -- took ages -- stainless steel or whatever the hell they are is feckin' hard. They're still pretty tight, hard going to get them on the frigging forks. Still may take them to an engineer (Alfa/Alpha Engineering or somesuch down off a small road off Wiri Station Rd are excellent and inexpensive) just to make my life easier.

Definitely do the clip-ons. I find it difficult to comprehend naked bikes with high `standard' bars -- at anything over 80kph you get blown around, and when cornerning the ergonomics are just up the tree. End up muscling the bike around instead of carefully guiding it through. Around town clip-ons below the yoke are fine, just remember to hold your body up with your stomach muscles (or stomach if you're fat enough) and your wrists will be fine.

I really want to fit clip ons to my bike, I hate the sit-up commuter position, especially on the motorway or open road. I don't have much money though so i am thinking I can either take the existing handle bar off and turn it upside down and 180 degrees to get a low rise bar, or make my own clip ons. I would love to have a look at some others clip ons first though.

You can make some clipons easy enough out of your old bars, some exhaust tube, some ferrules and a welder. You just cut the handley bits off your old bars, cut the exhaust tube to the right length to suit, cut a big slot in it, weld on the ferrules so that you can put a couple of bolts through to clamp the bars on tight to the forks and weld on the bars to the exhaust.

I did this, and in retrospect I would have been better off going down to cycletreads, rooting around in the secondhand clipons bin until I found some the right size, giving don $50 then going home and wacking them on. At least I have the satisfaction of doing it myself!

Yeah, i was thinking more along the lines of machining from solid 6061

With all due respect....but try to picture the mess if the bike does NOT go where you point it.....(especially since failures are most likely to occur in extreme situations....):blink:

A few extra dollars spent on your bike for quality components is cheap in the long term.....

We can get you clip ons in that size, woodcraft no less.

pm me for details. We can get most if not all sizes and for most model of bikes

Woodcraft 2 piece split clipons are specially designed to make installation and removal a snap. Our 2 piece design is race proven and makes it easy to service your clipons below the triple clamp without having do dis-assemble the entire front end. Special attention has also been taken to save weight wherever possible. The bars are 12” long and are easily adjusted to whatever custom width you desire.

Oh sorry I guess the 3 full seasons racing with exactly that solution wouldn't be test enough that this works then?
Actually in the case of my bike its in an even morre critical position

You must apparently know what you are doing then,and I did not meant to offend you..... but I don't believe that do it yourself solutions for essentials are recommended for novices....
Especialy not when perfectly suitable off the shelf items are available.....(Bikestore .)
Only make up your own if nothing is available, or if you can make a better product......(not all of us are gee wizz...:chase:)
