Interesting..... Definitely LOOKS cool.  | ||

I think it's been discussed before. I like the looks of it, but the obvious personal injury risks make it impractical. | ||
| Tdiddy |
I might run that on my bike. It really does look cool! What could it cost? | ||
| Buelltroll |
Ya because these bikes don't already sound like there gonna explode enough. Cant imagine that would NOT add more clatter to the already noisy drivetrain. It DOES look kickass though. (Message edited by Buelltroll on March 27, 2007) | ||

We ran this setup on our race bike during 2006. It does not add any 'clattering' although it adds a turbine like whine almost like a supercharger, particularly on the overrun. It was funny to sit in the grandstand at Brands Hatch and listen to people trying to figure out what kind of bike it was  The kit reduces the weight by around 10kg, and makes shifting easier too You can also run a high quality synthetic gear oil without the risk of clutch contamination. There are really no issues as far as safety is concerned and even the ultra keen pre-race technical scrutineers found no problems with this setup (If you manage to stick your hand or foot in there you are probably the person who would run over your own foot anyway). In order to fit this kit you need to strip the whole engine so that the bearings can be changed to sealed type and the oil passageway between the gearbox & primary needs to be welded closed. The kit was built more as a showcase for Free Spirits business than as a commercial kit, so only 3 or 4 have been made in total. Also worth a look is the lightweight swingarm on the bike pictured. This weighs an absolute fraction of the original and relocates the oil tank under the seat. | ||

Oh man! That setup is SWEET!! Too bad it isn't a bolt up project. I'm betting I'd have to take out a second mortgage on the house to buy it.  | ||

i was going to post a pic of this a while ago and see if anybody was running it...trojan answered that question....pretty cool though...i dont remember seeing the swingarm on the website...that could be interesting to have... | ||
| Cityxslicker |
the mud would get soo thick in that, Think I will keep mine stock | ||
| Sub65chris |
cost just for parts? | ||
| Firemanjim |
Trojan, As I am now running an open primary and belt on my B'ville bike I would sure be interested in obtaining such a kit. | ||

That looks Fierce! As long as the whine doesn't make it sound like the air fan...  | ||

That is stupid. If you want a chopper, Harley, or custom to put that BS on then buy one. This just ruins a Buell and I'm sure it makes it less comfortable and takes away lean angle making it pointless IMO. | ||

This just ruins a Buell and I'm sure it makes it less comfortable and takes away lean angle making it pointless IMO. You could not be further from the truth. If you don't like the look of it then that is fine, but don't try to make up fictitious reasons for it not working. I was one of the few people privileged to run this setup throughout 2006, so am probably a little more qualified to comment on it's performance. It does not make the bike uncomfortable (why would it?) and in fact makes gear changing and clutch operation much easier (it uses a dry clutch and the Free Spirits soft clutch). It certainly doesn't take away any lean angle, so unless you are John Hopkins or about to crash it doesn't make any different to handling or lean angle. This is actually no wider than your stock primary case,so there is plenty of other stuff that will hit the deck and ruin your day before this does, such as footrests, swingarm and gear/brake pedals. Take a look at this picture to see how ridiculous your assumption really is:  Think you would ground that or restrict your lean angle when cornering?  NOT A CHANCE!! | ||

I think it's cool and wish buell would put that on their bikes but with an acrylic cover over it like the see-through air boxes. That would look sweet! I wouldn't want it open like that to have my jeans caught in it. (Message edited by isham on March 28, 2007) | ||

I have been running a 3 inch open belt system on a Stroker Softtail for years, Unless your still in the 1960`s and wearing them Floppy Bell Bottom Jeans then No way in Hell are you going to get your pants caught in this system.... That is as Bad ASS as it gets.... And If I had the coin You can bet your Arse I wd. have one of them on my ride long ago... | ||

A chain will generally be more efficient than a belt when it comes to transfering power, but not if the chain is churning in an oil bath. In a racing application like this, a belt makes perfect sense, especially when it frees the clutch from the oil bath, too. A ventilated, lightweight primary cover would make that thing streetable, but I imagine most people would want it open for the bling (not me, I'd rather have a cool, ventilated cover). I like it, if for no other reason than it pisses some people off. | ||

Trojan, awesome input. I'm not interested in it, but nice to know the scoop.  +1 on the clear acrylic cases! That would be awesome to have color coordinated ones to go with the translucid bodywork! ~SM | ||

07xb12scg... Your not-so-humble-opinion is pointless IMO. | ||
| New12r |
I dig it, would love to have it on my bolt and it is a daily rider! I wouldn't want it open like that to have my jeans caught in it. What kind of jeans do you wear?? I know my leathers wont get caught in that! | ||
| Hogs |
New12R, HEs wearing them 1960`s Flared Bell Bottoms still  | ||
| Terribletim |
LOL! That's why I ride my Buell in the first place! I would run one on my softail if I hadn't spent all my money on a Buell! Have you seen the monster 4" from Primal Motorcycle Products? | ||

Trojan: That photo makes it look like the primary sticks out way past the foot peg. If you're running the exact same setup then the picture mislead me. | ||
| Terribletim |
It can't be stickin' out too far in that pic. The shifter is in front of the clutch support. | ||

"Unless your still in the 1960`s and wearing them Floppy Bell Bottom Jeans then No way in Hell are you going to get your pants caught in this system.... " I Definitely don't wear wrangler western jeans and cowboy boots, but I do like to wear fashionable straight leg jeans. I save my bells for he clubs. I'm glad swordsman thinks the acrylic cover would be cool. | ||
| Slaughter |
Acrylic cover wouldn't work other than on the floor of a bike show. There's loads of dust and gack that come off of a dry clutch that would coat the inside after just a couple starts and gear changes. You'd also build up a lot of heat without circulating air around the clutch. | ||

hi................could you please explain where a saving of 10 Kg comes from? original primary sprocket weight = 2.5 kg original primary chain around = 1.5 kg original primary cover = 1.9 kg original clutch basket around = 3.5 kg original hub (don`t know) - the primary sprocket shown of this belt drive system weights not less than 500 gram - the clutch basket is also around 1.5 kg if not more when you use a proper starter ring which has to be made from steel due to the material pairing requirements - the belt is also around 500 gram - the frame to fit the belt stuff is at least 500 gram based on this calculation your numeric weight saving is more like.......... 2.5 + 1.5 + 1.9 + 3.5 vs 0.5 + 0.5 + 0.5 + 1.5 kg that is a rotating mass saving of around 5 kg (and I have been generous) excluding the hub, which when using a dry clutch is most of the times heavier then in an oil cooled system..............having said that........it appears that parts of the original hub have been used.....or not? This is still a lot of weight saving, but the largest rotating mass on the primary side has been left untouched...........the alternator rotor, which due to the big radius and mass has the biggest impact. I am 100% with you regards that this alteration makes the bike run smoother...........but all the dirt from the road is sucked into this system and it is not possible to shield this easily (see Slaughters point). This works for the track, but not really on the street......... ..........so let me repeat my question what is the weight saving? Regards tiger | ||
| Terribletim |
I think most of the weight savings come from how effectively it lightens your wallet!  | ||

Terribletim: It can't be stickin' out too far in that pic. The shifter is in front of the clutch support. You know what? I didn't even notice that until you pointed it out! My bad. In this case I'm wrong. | ||
