Building Clip-ons

[Punx Clever]

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

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

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...

He was talking about titanium, not aluminum.

TAftonomos has a TI addiction and has stopped listening to reason.     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.   

[TAftonomos]

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

[Punx Clever]

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

[squidwood]

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.
