Being a poor college student, I find myself with two issues surrounding clip-ons for my s2r1000

1) Even half-decent clip-ons are bloody expensive
2) I have access to a machine shop with a nice CNC end-mill and a good metal supply.

That being said, I decided to build myself a set of clip ons instead of buying them.  I have a few questions though:

1) What down angle to most of you guys with clip-ons prefer?  I was thinking something like 7*
2) Rise.  No rise? 1"? 2"?  Any thoughts?
3) Bar length? 12"?
4) stock s2r100 forks... 50mm?

Here is a screenshot of my initial CAD model for refernce on how it will be made:

Any comments or suggestions?

Forks 50mm, yes
Most clip ons have 5 degree down angle, some are adjustable

I don't know how long the bars are supposed to be. Should be easy to check with manufacturers?

The question of rise is interesting - as far as I've been able to understand through my research it's mainly a question of what will suit you and your riding style/preferances. Add rise to position yourself more upright, but at the cost of race worthy control. No rise will require you to work hard with your core muscles OR suffer wrist pain. My personal reason to get clip ons is the sweep back angle - much better for my wrists (I hope).

Good luck - keep us posted [thumbsup]

I'm a fan of more rise and higher angles.  My wrists prefer it that way.  Flat and low looks cool, but you pay for it in comfort.

- find some tubing (wood/steel/whatever) and sit on the bike -- mockup what you want and then get someone to measure for yourself (and angles also)

- make sure you then take those measurements and check for tank clearance on the steering stops.  Problem is to regain tank clearance by lower bars, the bar angle widens -- thus why they get moved forward to give more lock-to-lock steering

- clip-ons I have made in the past tend to be shorter (@2" side) then regular bars.  Remember you are putting more of your weight onto the clip-ons -vs- just arm movement itself in the more upright seating position

- go make them and have fun then!

While we are talking clip-ons.


I have this thing called a lathe.

and I've got some 1" solid bar 6AL-4v Ti sitting here.

What wall thickness should I make the clip-on tubes?

Isn't the value of the bar stock higher than the cost of some basic clip-ons??  ???

Dunno what the metal is worth, but who cares.  It's sitting here, I don't have a use for it, and I want some trick clip on bars  [beer]

If we are talking aluminum (which I am) and 70mm x 80mm x 30mm block dimensions of your main bracket... hell no it isn't!
Aluminum bars big enough to make every part except the tubes are easy to source at around $30.
If you are talking about him wanting to turn down some 1" Ti stock for tubes... yeah.  Thats good and expensive.

I may just put different holes in the mounting blocks to accomodate different angles/rise.

PM'd you.  I've got chunks of magnesium laying around... [thumbsup]

He was talking about titanium, not aluminum.

TAftonomos has a TI addiction and has stopped listening to reason.   ;D  Since the TI stock is already (presumably) purchased is is no longer a question of saving money, but how do we get him to return to sainity.    [laugh]

If you guys really care, I got a 48" long 1" bar with certs for $30, so it's not THAT expensive..... :)

Really? I was looking at it and damn it sounded expensive...

but I do need some stock for the tubes themselves...

damnit.  Now I do need to build you a set.

Mag/Ti clipons... WTF man... would be great

you can buy used clip ons for around $40.00 if you look .
you will be into your clip ons a whole lot more than you think time,labor,material etc.
If it was this easy then everyone would do it.
Buy some used.

1) I looked.  Used clips that have the features and styling that I want are hard to come by and still cost $$
2) I enjoy workin' in the machine shop. I put new posts on a clutch drum once instead of buying a new clutch drum right off.  Worked good
    I can almost gaurantee you that I'll have one afternoon into building the mounts with the assistance of the shop foreman.
3) Materials: I am at 30 bux for the aluminum stock to make the brackets and tube clamps.  Just need to buy tubes. that puts me at 50 or so total.
4) It is this easy.  Trouble is that not everyone has a machine shop where they can do the work for free in their spare time.

Don't be a buzzkill

Build that shit and let us know how it turns out  [thumbsup]

Small update:

Got bored yesterday waiting for my aluminum bar to come in, so I rounded up some scrap in the machine shop and built a 50mm cylinder to mount the clamps on so i can cut the circular parts on a rotary table.
Today my material came in. HOORAY!

For finishing I'm thinking black powdercoat.  Ano would be too expensive and time consuming methinks.  Any suggestions?

Hmmm... black as in every other clip on? hmmm....

Maybe you could use your unique opportunity to make a surface/finish/pattern/personal logo which discretely shouts: I MADE THIS MYSELF
Wouldn't that be cheaper too? and more unique? You just have to make it subtle, but noticeable 8)

0.02 ;)

Now that you mention it... I have a signature I use for drawings that could probably be easily milled into the piece...

how does a leopard print ano sound for subtle?  8)

 [laugh]

 [thumbsup] [moto]

The ones I fabbed were .035  ;D  but that was with 3AL 2.5v Ti tube stock

Wow, that IS thin.....I can get .035 and .045 tube stock for pretty cheap as well (know a custom bicycle builder), but I thought that might be too thin.


I guess you asked the boss and got a big NO on the magnesium ehh?

Im 260 lbs, I tried to break em in a vice with a breaker bar, and they held fine.  I rode with em on for 2 years before selling the bike.  [thumbsup]

I may have to talk to you about your source, the one I went through last time wants 30 bucks a foot now  :o

Haven't got a chance to talk to the head honcho.  Only been able to go in later in the day... means #2 guy is there and he doesn't have the final say so I didn't ask.  Something tells me that flamable metal in a student shop is gonna get shut down though.  Sorry man.

Oh ooh - easy now, it was just an idea   ;D

everything is flammable :)

No worries, I'm impatient. My mill will be here soon enough.

Good to know on the Ti, and yeah, it's close to $30 a foot, but would be easier to get that then machine down 1" stock lol.

I rather impress the girls with girth.. [coffee]

But does it have certifications?

That must be why they call you can 'o tuna    ;)

Sorry chickened out on the Rockwell Hardness test. :-\
TA- I hope you are getting some sort of  class credit for this.... Not that having TI Clip-ons isn't its own reward.

lol, not me building them..  I was trying to talk the OP into building me a set of the clips in magnesium....by giving him somd [thumbsup]

Sadly, no class credit.  But, I am getting machine time.  That, and making the head-haunchos int he shop happier with me, thereby allowing more opportunity to build cool shit. 

Next up is a trellis timing belt cover  [thumbsup]

But, I have my mounting cylinder for the rotary table made, and I have all four of the blocks to make the clamps machined out and sized.  Next trip to the shop will be to bolt the pieces together so i can bore the hole for the forks... then mount it in the rotary table to make the outer profile of the pieces.

This is a pretty freakin cool project  [thumbsup] Thats all.

what machines are you running your parts on / are you using any software to program tool paths?

The actual parts? A manual end mill with rotary table.  This is old school man.

oh, well for whatever reason I thought you said you were using CNC machine(s).  I was just looking for the make

I thought I was going to, but in the end the shop foreman approved it on the condition that I milled it manually. I can get a make of the CNC machine after I go ino the shop next time.
