Project Fantic

This is just a quick update on the Fantic 200 twin-shock trials bike. 

It hasn't been abandoned exactly, but opening up the motor revealed some missing parts. The kick-start shaft is still there but the rest of the starting mechanism is missing - particularly a 20-tooth gear that's proving hard to find. There are a couple of other bits which seem to be common to other Minarelli motors but that 20-tooth sprocket is proving elusive.

The bike should start easily with a bump-start and this isn't a problem it it's just going to be a fun-bike. But to participate in trials events it needs to kick start.

Just for the sake of completion, below are some pictures of some other (small) progress that's been made of the project.

These images are take from the Mercenary Garage Instagram account...

Fantic 200 Trials - Original fuel tank with the oxide sanded off. I think I'll flame polish this for a better finish.

Fantic 200 Trials - The fuel tank was badly oxydised when I got the bike.

Fantic 200 Trials - The fuel tank with the oxide layer removed..

Fantic 200 Trials - Aluminium Side Stand, Swingarm Pivot and Rear Axle Assembly result in a weight saving of over a kilo.

Fantic 200 Trials - Rear Drum Brake Parts. Lighter, but just a little.

Drillium

This is what 25 grams looks like...
This is what -25 grams looks like...


Generally when I'm building motorcycles I try to make them as light as possible. On a regular bike there is usually low hanging fruit like steel mudguards, heavy clocks and headlights, indicators, passenger pegs and suchlike that can be easily removed or replaced with lighter parts to reduce weight.

The Fantic is already pretty spartan and there isn't really anything that can be removed without affecting the functionality of the machine. So in order to reduce weight I'm planning on replacing some of the steel parts with fabricated aluminium parts and then drilling holes in everything.

So I picked up a pair of cheap Ebay shorty brake and clutch levers to replace the mangled stock ones and I was curious to see how much weight could be removed by drilling them.

The stock levers weighed about 300 grams per pair. The new Ebay levers were shorter and generally less robust and weighed about 250 grams per pair. Drilling the levers and replacing the plated steel cable adjusters with alloy ones reduced the weight to about 200 grams.

So 25 grams per lever isn't very much. But by replacing the stock levers with lighter ones and then taking a little care to lighten those parts further, I was able to achieve an overall weight reduction of about 100 grams.

I'm very happy with this. Am I going to notice 100 grams off an 87 kilogram bike? Probably not. But it's a subtle thing. That 100 grams is high up and far from the centre of gravity so maybe, just maybe it will have an affect on the moment of inertia.

And if I can remove 100 grams here and a 100 grams there, well those 100 grams might just add up to a noticeable difference. And if not, well it's still all good.

Dunno. I started off this drilling thing just out of curiosity but I'm quite pleased with the result.

Fantic 200

I just picked this up. I'm not sure why. It just sort of... spoke to me.

It's a 1978 1980 Fantic 200 Trials Bike. I haven't had a good look at it yet but it seems to be almost all there. More to follow.
