Not really a new product, it was released in 2006, the Auto Clutch is still quite unknown and misunderstood by those who heard about it. First, imagine riding up to a stop light with your bike in gear and not having to hold the clutch in. Yes, you can. When the light turns green, twist the throttle and ride away. Pretty cool. Ready to up shift ? Pull the clutch and shift as usual.. except the clutch lever can be pulled with one finger. Awesome. Downshift the same way you shift. Want neutral? Pull in the clutch and then shift to neutral. Nothing new to learn. So, how does it work? The clutch pressure plate is replaced with a new unit which works by applying centrifugal pressure to your clutch pack. Engine speed does the work that is normally done by springs. When you pull the clutch, you are releasing only the pressure plate and not the clutch pack. Hey, you had to think about it. Grandeur Cycle.
Cool. But must take a little bit of tome to adapt.
So Cyril have you rode a bike with this installed, or has anyone else. Because I’m wondering exactly how good it works in the real world because on paper it looks awesome.
i have one in my 420 h.p. twin engine bike, one also ion the twin engined cheese hualer, and have used it as a cheater part for my wealthy (newbie) customers on bobbers who couldnt operate a foot clutch with confidence. they work plain and simple. dont buy the cheap immatation buy american from granduer or efm auto clutch.we are currently building a new harley based drag bike and plan on using the efm clutch becuase of its lock up qualities.
The autoclutch works great as long as you keep the rpm’s up, if you don’t your clutch is slipping. I’ve ran one for the last two years on my custom. I checked my clutch plates a few weeks ago and they were starting to wear so I went back to the stock BDL pressure plate.
Yep, that’s correct- have to be a bit more decisive with the throttle as far as on/off, else the clutch plates wear a bit more, but I’m at 8K miles with my Grandeur, no prob- just a bit of clutch dust showing in the case oil, I’d say I have a bit more than half the clutch lining left.
For me, I like it- I have a foot clutch and no front brake, and the Grandeur makes the bike a lot less of a headache to ride around in stop-and-go traffic; Just be sure to “launch” the bike a bit as you take off.
For me, replacing clutch plates more frequently is worth the trade-off. Otherwise, the Grandeur clutch has worked exactly as advertised- as a bonus, the way it’s designed, the clutch clamps harder as centrifugal forces increase- so it should work well with big motors (mine is on an 80 cid Evo).
Oh ya- and be sure to put something under your wheel to stop the bike from rolling off when parked (learned that one the hard way- lol).
BMW motorcycles have used automotive style clutches for 75 plus years
Installed one of these on a O School bike with foot clutch and no front brake. We’re in Neveada and its very dusty here. Worked for a few hours and the bearings wouldn’t ramp and release. Our customer went to start his bike and it took off into a another bike, he broke his wrist. Another bike shop friend installed one as well with the same reults, customer launched into a car. When the plate is disassembled and cleaned it works awesome, but any dirt particules in those ramps and it will not free wheel. We thought it may work good if the system was in an inner out primary setup.
Lucky both of these customers supplied the shops with the Grandeur clutch or we would be in court.
Another example why it’s kinda smart to fire up your scoot in neutral- the Grandeur doesn’t repeal the laws of physics;
I have 8K miles on mine, never noticed any plates sticking. but like any bike, when plates stick, roll the bike forward and back a bit, that will break them free…..
Cryil, the auto clutch is standard equipment on our 300 Disruptor kit bike. We DO NOT USE A CLTUCH LEVER. The bike is full auto. We love this product, as do our customers. We are a distibutor for EFM, who makes all the clutches, including the ones for Grandeur. The owner of EFM will be in our booth talking about the product at the V-Twin Expo. So if any one has any questions they can stop by our booth at the show and have them answered by the orginator of the auto-clutch himself.
The auto clutch works great. I have been riding with mine for about 2 years now. That said, it can be dangerous. If you forget that you have in stalled this clutch,and that you can start it in gear and rev it will take off like a bat outta hell! I did have to learn the hard way. But in traffic it is a great piece of technology.
Wow! It’s really cool. Respect to admin.
Can anyone tell me the difference between the grandeur/EMF vs. the cheaper unit. Pictures look exactly the same and I have also seenboth units up close. Couldn’t tell much of a difference.
two things}
a- if the bike rolls when parked and should be or has to be started in neutral or when clutched does that not mean if bike needs to be pushed to start if in case of battery dies it will not engage.
b- for those of us living and riding more north during cold weather, when choked and idle is high during start bike stands chance of lurching forward
