Today we received our last brake disc for the Buell Family from Galfer who is doing all our production. It is not treated and not hardened yet but this is just for fitting. We will nail this one on our wall (-: We are very proud to tell that we are the only company in the world that have developed all brake disc front and rear and all brake pads, in different compounds with TUV for all Buell models from 1984 till 2010. We will keep you all on the road. Here you can find the products: http://bit.ly/fW9x3v | ||

So no caliper/pad combinations yet? Have you considered a lightweight rear pulley for the 1125r? That thing weights a ton, and I'd love a better option. | ||

"Have you considered a lightweight rear pulley for the 1125r?" Can I get an Amen on that, brother? | ||
| Easyrider |
not yet... It's not a priority part to develop | ||

Jdugger, pulley does not weigh much! only 1671gr  http://imageshack.us/photo/my-images/819/010120082 200.jpg/ | ||

Thanks Easyrider!! Everyone that owns a BUELL should be singing your praises. | ||

I've come to find it ironic that all of the marketing hooplah around unsprung weight advantages turns out to not be true, at least for the rear wheel. Compensated pulley + belt + rear pulley > steel drive sprocket + 520 chain + Al rear sprocket.  Sure, the belt weighs less than the chain. But, the belt pulleys weigh a lot more than sprockets. | ||
| Zecca |
exactly! the pulley of Cr weighs more! almost 2kg we have to take into account, the belt tensioner which rotates along with the set | ||

>>> I've come to find it ironic that all of the marketing hooplah around unsprung weight advantages turns out to not be true, at least for the rear wheel. Could you please clarify what you mean by "all of the marketing hoopla"? I have no idea what you are claiming is not true about anything advertised by Buell or EBR concerning their rear wheel(s). Are you saying that a significantly reduced unsprung weight (mass really) is not beneficial?  It sounds like you are trying to compare apples to oranges and then make up your own straw man argument. Buell or EBR never claimed that a belt drive was overall lighter than a chain drive system. What they claimed was that a lighter wheel and less unsprung mass is better than more. There are other benefits of a belt final drive that made it a good choice for a street bike, namely that it is quiet, maintenance free, elastically forgiving, and it eliminates backlash (driveline slop). | ||

Can we keep this topic, ontopic (-; (Message edited by Easyrider on December 01, 2011) | ||

>>> Compensated pulley + belt + rear pulley > steel drive sprocket + 520 chain + Al rear sprocket. You forgot to include the rear wheel hub-mounted compensator. Also not sure why you are including the drive sprocket in the equation, it's not part of the rear wheel or unsprung mass. Is the resulting relation still even true? belt + rear pulley > 520 chain + Al rear sprocket + hub-mounted cush-drive? Do any literbike class motorcycles even come stock with 520 series chains and aluminum rear sprockets? If not, then again you are comparing apples to oranges, and thus in the end your relation is apples to oranges2.  | ||

Sorry Dris. By all means start a new topic whenever you like to share news about your new brake products. I'm still in wonder how you are able to develop and offer such rare products. | ||
| Easyrider |
What is it you like to understand about our product development blake | ||
| Blake |
Bad wording. My intent was to say that I marvel at what you are accomplishing. | ||

+1 Blake I've been waiting on the caliper announcement and new rotors myself. I think it's great to have supporting 3rd party vendors for our machines. As for the other stufff... I'm basically done trying to argue sense with you. The belt apparatus is heavy, it weighs more than a chain drive (and yea, it's typical to put a 520 on a 1,000cc race bike and just change it more often), and your concern is debating minuscule "facts", not the stuff that makes a difference for us guys racing the things day in and out. So, if someone created a really light rear sprocket for our wheels, not one that weighed 1.6+kg like the OEM piece, it would make a difference for us. | ||

>>> I'm basically done trying to argue It's not miniscule facts when you spout off that "I've come to find it ironic that all of the marketing hooplah around unsprung weight advantages turns out to not be true, at least for the rear wheel" and are asked what exactly you are talking about. When you mis-speak, simply admit it. What you stated is flat out untrue. I didn't ask if 520 chains are put on race bikes. I asked if they and aluminum sprockets come stock on liter-bikes. You are comparing a stock belt drive to aftermarket racing components? Buell racers also put chain drives on their bikes. So again, I don't see what point your are trying to make, comparing a stock belt drive to a modified chain drive racing setup? What is your point? Are you still trying to contend that less unsprung mass is not beneficial? | ||
| Jdugger |
are you paid to be this belligerent? Go get a scale and a couple of final drive systems. I'm not contending anything w you because all you will do is blindly fanboy on buell and change the subject constantly until you feel like you have won the argument. | ||

I would like to know if the board software has a feature that would allow me to turn-off all posts in the 1125 forum that come from people who don't own an 1125. | ||

I think it is great that some entrepreneurs are tooling up to support our bikes. This is how we will keep these bikes on the road 15 to 20 years from now. I know some of you could care less because you change bikes like women change fashions with the season. | ||

Interesting comment about the CR pulley weighing more then that of the R. I bought a CR 76 tooth pulley for the project bike and I can assure you that it is quite a bit lighter then the smaller 70 tooth pulley used on the R (sorry no digital scale to give you exact numbers) Definitely going with belt final drive for the project though  | ||
| Nattyx1 |
AJ? How is a larger pulley gonna be lighter than a smaller pulley -- does that make sense? The CR pulley is bigger, shortening the gearing. Bigger, all other things being equal, has got to be heavier. I didn't hear anything about a materials change or wall-spec thickness or diminished # of spokes between the R and CR models... did anyone else? Maybe I just missed this? | ||
| Aj2010 |
I would say all other things are NOT equal. Since the paint looks the same I'd have to definitely go with a material change being the reason for the weight reduction. I just hope that quicker wear is not an issue. | ||
| Jdugger |
AJ, This is very surprising to me. Have you weighed both? | ||
| Hybridmomentspass |
makes no sense. | ||

I sent Rizoma a note yesterday asking them to produce a billet pulley for the 1125r. They made one for the XB, and it looks better, but not totally sure about the weight. Dark Horse Moto also made one for a while for the XB. They indicated they would look at it, but I know what that means. It's really hard to convince a 3rd party vendor to produce a part for a bike that's not only out of production, but didn't sell that many to begin with. The better long term solution is probably the chain drive kit, anyway. Lots of parts available, and other than the wheel spacers none of it is proprietary. Lighter, too, and since none of the Buell race wheels use a cush on the rear, an Aluminum sprocket would be the lowest unsprung weight. The 1190 has a compensating front sprocket... could be an interesting way to go longer term with these bikes as belts and pulleys become hard to find, or absolute lowest weight is the goal. | ||

the 1125 is a pretty light bike the 1125 has pretty low unsprung weight, thanks to some nice EB engineering the belt drive system is so quiet, clean and easy, it's great for STREET USE That's enough for me. Sounds like a solution looking for a problem (Message edited by sprintst on December 05, 2011) | ||

Jdugger, I see you riding an 1190 in the near future or a derivative of it. Seems like from a components standpoint, it has all the stuff you'll need to maximize your efforts on the track. | ||
| Jdugger |
The only real drawbacks of the 1190 are 1, cost, and 2, they are a "big bike", so there's relatively few classes you can race one in. The 1125r races 750s, so there's more options. Sprint, the OEM Buell wheels are not competitively light. At the time they came out, they were, especially the front, but improvements in Japanese wheels changed that. By 2008, front wheel and brake system weights were roughly the same, and the rear wheel is a good bit heavier. Upgrading to the Buell Race Mg wheels does help. The rear wheel alone will save 3lbs, and you can save another 6 or so going to a chain drive (Al rear sprocket) and smaller rear brake rotor. But, the Mg wheels can't be used, for long, with the belt drive. The belt's tension will slowly (say, 1,000 track miles) destroy the journals of the wheel itself. I am a big fan of the belt drive, actually, but for racing its got drawbacks even beyond the obvious "can't change gearing". Lack of wheel options and the stress on bearings and the wheels themselves are two of the more unusual ones I've discovered over time. And, now that I have a 2007 Honda 600, I'm also discovering that weight is one of them, too Some data on wheel weights: http://www.badweatherbikers.com/buell/messages/290 431/600126.html?1287696950 |
