If it wants to go too fast in low gear when on downhills, shift up to second gear and turn off the ignition with those ever so handy little red buttons on the right (starboard) handle bar.

so that's what that dam things for? i thought it was there to run your battery down while cranking the electric starter

Ha-Ha, but no that is not what they are there for. They are there because a bunch of politicians decided we absolutley had to have them in order to ride the d++++d things without getting hurt.

I dont use the motor going down hills "real hills"
clutch in or pick nutrual...
The motor has no idea what the rear wheel is doing..
I do..

but it;s a diffrent ball game with the rekluse auto/manual clutch..
dab the rear brake and it drops out /disingages free wheels..
blip the throttle and it reingages..

Rekluse auto manual clutch? Sounds like the real deal. I like to have some engine drag going down "real" hills. Just my opinion, and comfort zone, I guess. On older bikes, I used the compression release to do the same thing. The compression release had the advantage over switching off of being variable in action.

the two sections of the unit have wedge shaped weights between them..
the unit exspands as the revs come up compressing the clutch plates but
you can still pull the clutch lever opening the clutch pack more than what the rekluse
unit can exspand giving a full manual clutch still...

Pretty slick! Thanks for the illustrated info. Someone on here will want one. Remember: "He who dies with the most toys, wins!".

I was never a great rider, but like a lot of people, I was always fascinated by people who were great riders. Now we have this fantastic resource, you tube. I like to watch pre-65 trials on youtube. If you live in the Eastern or far Northwestern parts of the United States, you can learn a lot about handling a bike, off road, from these guys. Some of these guys are riding rigid frame motorcycles, and, if you watch closely, they are not at any real disadvantage. They use their legs for rear suspension. Some of the sections they ride through are tougher than you can imagine. Now when you ride trials, you loose points for a "dab", More points for "footing", and if you drop the little beastie, or kill the engine without being able to restart without footing, you loose five points, which means you've blown the section. When you listen to the Commentary, supposedly in English, maybe you will understand when he talks about points. Almost all of these bikes are running a 21 inch front, and an 18 inch rear, just like a Hawk. They are running trials tires, of course. Note how much these guys ride standing up. But that isn't all they are doing. They are shifting their weight, left and right, on the footpegs, as well as front to rear. If you like wheelies, you'll get to see the practical use of wheelies. So tune in, and enjoy. You might call this a College Education in riding the rough stuff.

If you watched some of those trials videos, but were kind of overwhelmed with information, I found another one that may be even better for you guys. Google up to youtube-Mick's garden and especially watch the guy on the Honda twin-shock bike. You can learn a lot from just watching him, and then practicing, of course. Notice that these guys all have pretty low tire pressure, particularly at the rear. I was particularly impressed with this guys ability to lock the front tire, lift the rear, and move the rear any which way he wanted it. Gonna' take a lot of practicing to be able to do this. Gives you an excuse to ride, right? Another thing I noticed is most of these guys have quick-turn throttles (twistgrips). When those pulley type straight out twist grips came out, I bought one. Worked great FOR ME. Might not work so good for you. But some kind of quick turn twistgrip helps a bunch when you are riding slow, through the rocks, or whenever.

Not normaly..

Trials bikes tend to use a 1/2 turn throttle not a 1/4 turn...
1/4 turn "quick action" makes the throttle action to twitchy
the smallest movment while turning going over what ever
and catapulted forward with a 1/4 turn...

The vid you watched Micks Garden is...
Mick Andrews a multi world trials champ... The Ossa MAR is the bike he developed
and won a couple world titles on..
MAR = Mick Andrews Replica

If yer want to see a trails rider... google Tony Bou
this guy isn't human... very very few mortals are even
close to that level..

one of the reasons vintage trials has be come so big
these guys are SO good that joe avarage can't come close
to getting around the courses these guys ride..

vintage trials old school bikes on old school courses
with the old rules...

I picked vintage trials to help people ride because they are more like the bikes we ride. The guys I remember riding Tiger Cubs in So. California used quick turn throttles, the guys with the big bangers used used the normal 1/2 turn twistgrip. Thanks for your input on this subject. I appreciate it.

I forgot to mention that you should run the 17 tooth front sprocket because it is kinder to the chain, and leads to longer chain life. Try to make all the gearing changes you desire in the rear sprocket. So, let us say, you have the standard 50 tooth sprocket on the rear. With the 15 tooth front sprocket, the ratio is 3.33. With a 17 front, the ratio is 2.94 and change. An 11.7 boost in speed at the same rpm, assuming the engine can pull it. They claim 57-58 mph, as I recall. 57 mph plus 11.7 % boost comes up to about 64 mph, if my math is right. But what about low gear, you say. At an idle of speed of 1600, it increases about 1/2 mile per hour, to 4.5.

I kinda like the Urban Trial videos, I want to learn to do that, Get into trouble around here though

Hey ARH check this out. My company had a bunch of electric vehicles come out to demonstrate there wares and it was supposed to include Zero Motorcycles. Alas, they did not show. I was bummed because they allowed folks to road test some very high end vehicles. ( a couple of porsches, an audi BMW... etc) There were even electric bicycles.

I noticed in there sales brochures a silly huge rear sprocket, the rear is 132T and the front is 25T. Why Pray-tell?

so they don't need a reduction box with the drag of gears/bearing/oil
Oil is the biggest HP robbing compont in a motor and the weight & space needed...
all that would shorten distance on a charge

Yeah, interesting. My first guess would be that they can get longer range by using a lightly loaded motor. This is a different kind of electric motor than what we are used to. A starter motor's Maximum torque is at stall, for instance. Note where this motor's peak torque is.
