Sprockets, brakes and break pads.

[P3aK]

Does anyone know of any front sprockets that are lightened (drilled holes around the center hole to remove weight) that fit our bikes? 

Supersprox and Renthal both have, but I can't find any that fit our bike.

Are there any other bikes that use the same type of sprockets as the Steamer? Like Honda, Yamaha and the likes with more abundant selection of items. What are we actually looking at for for example front and rear sprockets?

Front should only be the axel size and the splines right? (Yeah of course the number of teeth) What are these dimensions/measurements? And the rear? Is there a bolt hole pattern that has to be the same? What is the bolt pattern?

I'm currently out of country so I can't look at the bike myself.

And what about break discs? I know there's a Galfer wave rotor (DF005W) but they're pretty darned expensive. Any other wave rotor options? And are there any light weight carriers for the rotors that one can upgrade to? I'm starting to hunt for weight everywhere.

Break pads... There seem to be a common idea that EBC are top of the line. Are there any other bikes that use the same pads as we do? It's becoming hard to find the Steamer in motorcycle online shops. And I'm still dreaming of the 6pot Alcon, Bullet, Muller or any other brand. What kind of pads would one use for those? The same as the 4pots?

Oh, and do the Girly or any of the other Triumphs use the same sprockets, brake discs, break pads (ignoring number of sprocket teeth) as the Steamer? Many other models are easier to find in the stores.

EDIT
I just figured out all Triumph use the same rear and front sprockets (bar the teeth)  except for Bonneville because it uses 525 chain
END EDIT

Having just "upgraded" to Galfer wave rotors and Carbone Lorraine pads, I'd recommend you save your money and stick to the standard EBC stuff.

Erm, what will you gain by losing a fraction of an ounce? Just curious.

[P3aK]

Interesting Ssevy,  so you recon it isn't worth the money for the performance one gets? Is the combo you have worse than EBC or equal (if you have had others and can compare)?

Nickjtc, well obviously not much at all. But it's a reduction in a place where reduction matters more compared to other places. And as I need to replace it anyway and the difference of cost doesn't seem to be much or any, I might as well try to get one. I see it more as a farkel. Just having trouble finding one that fits our bikes.

You'll save more weight and even gain a little power by removing the noise attenuators in the left casings.

Most of the weight is in the frame and the engine, not a lot you can do about either.

[P3aK]

I have to admit I have no clue what "noise attenuators" are. Where are they and what do they look like?

I know, the frame and the engine are what they are (one would be forgiven for believing they're made out of cast lead).

But that kind of brings it to my point, what I can do. And if it doesn't cost me any more (except time to find it) why shouldn't I?

Anyway I've emailed Supersprox and will see what they reply.

When you have this all done please pop the bike on the weigh bridge and find out what it comes out at.

I have long suspected that there is at least 10kg to come out of the exhaust system alone!

[nickjtc]

Isn't it a given that the most weight that can easily be lost from the motorcycle is actually from the person sitting on top of it...?? :icon_wink:

[Geoff W]

I reckon Nick could be about right, the Motad Venoms on mine must be 5-10kg lighter , and several decibels louder than the original pipes. Also they reduce weight from high up on the bike which should help with the top heavy feel.

Lotta weight loss with the venoms.

The standard rotors with EBC semi-sintered pads stopped better, even before I rebuilt the calipers with new seals and used red rubber grease! Not sure if it is the Galfer rotors, the Carbone Lorraine pads, or both that suck? Right now just running them and using them hard to try to get them to improve with use - probably beating a dead horse. My first switch will be back to EBC pads, and then if necessary, different rotors. Expensive experiment for sure

[P3aK]

Very interesting information ssevy. I sure will want to hear what you think if you change the pads first. I had high expectations of the galfers. Might have to reassess depending on your findings.

My idea was to eventually get new steel braided brake hoses, galfer rotors, EBC pads and... should I ever win the lottery... 6-pot calipers.

Nick, yes I will definitely put it on a scale and find out the weight. I meant to weigh the original exhaust system and the Motad 3-1 I bought from you and compare straight off. But I forgot about it before I put the Motad on the bike. If I ever take it off I'll do it. But I can't be bothered to take it off now just for that.

Geoff/GavD, yeah already got the 3-1 Motad on the bike and it makes a difference. But want to loose more weight in other places. Without going mental and start cutting the frame and such. I've taken away the skid plate and pipe frame that connect it also to save on some more.

Nickjtc, I'm a skinny guy at 63kgs already. If I loose more weight I'd say I'm looking for trouble. I'm in the game of trying to gain weight. I keep eating steakes but nothing happens. 

[Sin_Tiger]

Since you're serious about this and willing to experiment I'll happily put some details of the internals up when I get home next week.

[John Stenhouse]

Better idea, go on a diet, I lost more than I could ever take off the bike, 20kgs makes a hell of a difference.

[Sin_Tiger]

20kgs makes a hell of a difference.

It's the wind resistance that's the real killer
