My starting rollers

[Ariel Badger]

The faster my Badger gets the harder she is to start. She kicks back brutally and we are going to increase the compression ratio to 12-1 over the winter, something needed to be done.
I decided to build some starting rollers. I was given 7 foot of 4" pipe and purchased some bearings on line this is the result of a lot of machining and welding.
The principle is this for those of you without a technical background...
(Note this is a two person operation)
The van is driven up the ramp and the rear wheel drops into the rollers clear of the ground. The bike is reversed up the ramp next to the van.
Second gear selected on the bike and valve decompresser lifted (you could use the clutch), van started and first gear selected and clutch dropped.
Because of the van's differential gear the wheel that is clear of the ground breaks free and spins the rollers up driving the back wheel of the bike.
The decompresser is dropped and the throttle opened, bike fires and you pull the clutch in whilst blipping the throttle. At this the van man de-clutches, selects neutral and applies the hand-brake.
With the rollers locked by the van brake the bike man selects first and drops the clutch, bike jumps out of the rollers and is ready to race.

Very simple in principle, I've seen it whereby a 2nd bike has been used to bump start the bike not a van though. Makes more sense to use the transport to get you going.

I've seen it done by van a number of times before. It makes a lot of sense because the van will have loads of torque.

Roller starting a bike with another bike sounds pretty difficult to me... unless you're using a Goldwing!

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

I do not claim to have invented the technique. It is a very simple and ( provided you have the means of manufacture) cheap solution to starting. They are now painted and the rollers themselves are coated with grit for extra traction.

I still preffer watching people do the push it round the padock method of starting. Its great fun watching 2 guys try to push start a classic ducati that needs the back wheel doing about 40mph

Cool bit of kit.

What was the most hassle in contruction, getting the right bearings?

Do the rollers sit on an axle all the way through or just studs at either end that sit into the bearing?

They are just short stubs. The bearings were just stock items of Ebay, I bored the end plates to suit. Biggest problem was that the pipe was old and slightly oval from the scourging action of an abrasive fluid and it caused problems with concentric location of the bearings. I hit it with a hammer quite a lot and it works.

Wally, this might have already been asked elsewhere on the forum but was your badger in MCN last week?

Cool little project,

Joe

Much less imaginitive, but I prefer one of these:

Hi

Nicely done. Just don't ever try using it on a van with an LSD.

All the best

Wally's Badger is one of a kind iirc?

So if there was an Ariel Badger, it was his!
