I know of a Motorbike Engineering company that can make these - most likely for a reduced price.
If anyone has a spare set or can overlay a picture of them with some measurements then I'll ask for a price.

if that engineering company could make bungs instead, that would be a lot simpler and just as effective, probably cheaper to make as well.

There's a company in the States that do them for the Hawk ( www.hiperform.com/frame_sliders.htm), so should be possible for a reasonable cost, I would have thought. |

All you'd need is the same slightly longer, stainless engine mount bolt as is used to mount those crash bars, and some nice long bungs to protect the rad. I would definately pay for that seeing as I'd probably be able to use them with the fairing as well. It just needs to be a hard wearing composite tube of whatever, even metal? (titanium sliders, for sparky fun  ) surely much easier to manufacture, no special tools, can be made in any batch quantities. If someone can find a company that could do this, I will pledge to get one of the lot straight away, it's basically top of my list for stuff I'd like to add to my bike. |

If it's just 'crash-bungs' which people are after, then a simple peice of Polyurethane rod (probably around 30-50mm Diameter), stick it in a lathe to shape, add some stainless fasteners = job done
I reckon 2x sets out of a £20 peice of rod, a replacement front engine bolt, extended in length to mount them, £10-£15. Plus some tooling time & associated attatchments.
My estimates would be £30-£50 a set - which is near-ish the same a R&G 'bungs'. This is just a guess & not what I've spoken to any companies about.
Next time I'm visiting Maz I'll ask about the costs & get a couple of sets made for some-one to review.

how hard wearing is polyurethane? What are commercial bungs made of?
The hawk bungs look quite long and I would be concerned about the material fracturing if it digs in/catches the ground, or if it wears too fast.
Would metal be a better material in any way?
Also, those R&G bung kits, are they universal?

I believe polyurethane come in different grades, just like aluminium or S/S. Depending on the grade, depends on it's use.
High(er) spec cars use Poly' bushes for suspension, I think skate-board wheels are made of them also.
There's also high density nylon which I don't know anything about.
'Crash-bungs' are designed to be the 1st point of contact when the bike goes down & are very sturdy & lasts a few falls.
'Crash-mushroom' take the impact & deform - acting like a crumple-zone & have to be replaced each time.
I wouldn't trust either of them over 10mph to protect my bike - above those speeds there's too much mass-movement.
The Engineer I know used to race the TT & shuold know the best type of materials & mountings to either protect or delibertly sheer if the forces are too great (which should protect the font engine mount bolt)

To get a 'feeler' on the sort of prices which is considered resonable, how much would people be considering to to exchange for.
- A Set of 'crash-bars' similar in style to the ebay link above?
- A Set of 'crush-bungs', (with replacement front engine bolt) similar to the R&G's?
Also a 'rough' idea on how many people would want them. i,e: If I ask the company to make 5x of each then I might be able to get a very good discount.
my thoughts would be £50 delivered for the bars & £35-£40-ish for the bungs & I'm going to put my name down for some bungs.

I'd like to put my name down for some bungs. Just need to check how long they'll be, I've got a fairing on and theres quite a gap between the end of the frame and the fairing. If you could get dimensions for both then I'll let you know my choice.
If I can fit a set of bars down there then I might give them a try, more places to clamp stuff like lights and tool tubs on, i'll have to measure and think.

Sounds v good to me. Thanks for your efforts in looking into this. |
