Im not a fan of the way some Shark Fins are so far away from the chain, like this Puig model and many more. IMO it gives more room to get your toes in.

By making a completely flat Carbon Fibre peice it could be fixed to the inside of the swing arm (tap 4 allen bolts), has got 5mm distance from the chain and is more discreet. Im not sure if it will be track legal though.

The design was cut out of the flat CF board by jigsawing the holes out and tidying with the dremel.

It was very cheap to do, took less than 2 hours total to make and is very strong and light. What do you guys think???

Let me get this straight. You are running completely stock suspension, riding on public roads and your biggest concern for increasing your personal safety is to make sure your foot doesn't get tangled up in your drive chain when you crash.

Are you telling me that they have now made Toe Guards mandatory for trackdays over there??? I want to see the rules for that! Maybe in racing, but for common track days that is just ridiculous...

It might not be on all tracks, but the school i wanted to attend said you could use your own bike if the lights are taped over, oil filter is lockwired and you have a toe guard.

Anyway, spit it out LDH, whats all this animosity about?

Trust me you don't need them for trackdays here.

I do think it looks quite good though :)

Cheers man:cool: I wish i could come and work for you mrgrn, learn how to do CarbonPartz properly :hail:

Ive been asked by a mate to see if i could supply oversized toeguards for 60T+ sprockets for the UK stunt community.
Im amazed at what i can do with composites but at the same time i cant seem to get any consistency, my parts can come out brittle or bendy, not to mention how i get resin everywhere.

Well im very pleased with myself for making that, its only small but its the first time something has come out really tidy.

mrgrn - Thanks so much for the offer of help, your works awesome. I took up composites as a way to try and make bespoke stuff, parts that you cant get from a mold. It would be great if i could email you my next project and get a quick bit of guidence :th_salute:

Unfortunately mate, your basic design is shite. You have an internal V which could easily snag a toe or finger.
It's called a shark fin for a reason, it needs to be that shape to push your pinkies away from the chain and sprocket.

Having said that, the basic idea seems good, fitted tight to the chain, it just needs to be a different shape.

How much does it interfere with fitting the rear wheel as it is?

Thanks for your thoughts John - Well ive designed it like that after looking at some of the new motocross toe guards, they dont use the shark fin shape, instead guard that encompases the chain so your toes cant go through. I figured that shape would keep my toes away from the spinning chain.

My previous bought shark fin is so far off the chain my boot toe could get cought in that chain/sprocket nasty with no problem, also if its a shark shape there would be a V with a spinning chain to trap the toe. So i still recon this shape could be better but untill my toes come off we will probably never know :th_SmlyROFL:

This toe guard is 4mm thick and its 10cm off any rear wheel fittings.



:cool::cool:Cheers mrgrn

That's it though, isn't it? I really, really like the idea, BUT your guard DOESN'T encompass the chain, it's only on one side.

Where you at anyway matey, always good to see UK faces on here

Its only 5mm off the chain and i doubt your toe could get pulled through there, if it could then that would render shark design at 5CM off chain useless. Fingers wouldnt stand a chance.

Im Macclesfield, Cheshire - thats 215 miles from you, which is a shame cos im looking for a new mate to teach me to ride track properly. I did have great guy 2 months ago and he tested the blade for me but his phone went off.

I'm sure we can meet up a a track or two, but as to teach, don't listen to me, i'm crap!

I#m doing Brands GP this monday with No Limits, and I'm having a full days 1:1 instruction. It's only £100 for the tuition (track day is £200 on top mind you, but I love Brands GP).

I'll be testing my new QS as well ;)

" don't listen to me, i'm crap!" ha ha, thats cool, well you look good anyway and im sure your way up on me :)

£100 for 1:1 full day is amazing value hey? but £200 for a track day is expensive but i dont know anything about the No Limits event.

Brands is 2 hours away from me and ive no trailor, so im looking to do Donnington or Alton Park.

Id love a QS but ive told myself to hold off on the exhaust & ECU Map etc till next year, something to look forward to. hope it all works smooth.

Ant,

My first impression is that the angles don't fit the flow of the bike. If the guard was angled similar to my outline it would be more aesthetically pleasing and IMO it should extend on the bottom past the chain itself.

You're on the right track though.
