What did I learn today – Trial by Combat

Who said motorcyclists aren’t reasonable people? Especially the old school bikers.

And what better way to reason and argue a  £25 fine than trial by combat?!?

In December 2002, a 60-year-old mechanic named Leon Humphreys was fined £25 for failing to notify the Driver and Vehicle Licensing Agency (DVLA) that he had removed his Suzuki motorcycle from road usage. He refused to pay and claimed that he had the right, under medieval law, to choose a trial by combat with a “champion” nominated by the DVLA. This claim was denied by a court of magistrates in Bury St Edmunds, and he was further fined.[18]

I say let them throw down the gauntlet (or motorcycle glove) and allow for a champion of justice to go face to face with a champion of defense. That is if the defender can’t fend for himself that is.


Disclaimer : the old guy in the photo is not Leon Humphreys. That’s all.

Custom Bike Builder Website Concept

Sometimes I wonder why I studied Engineering and not something useful like website design and building. It would have made little things like creating an awesome Custom Bike Builder website a lot easier. Now I’m stuck with all these ideas but fail to execute.

The concept:

A Custom Bike Builder website/mobile app that allows the user to mock-up their vision.


The Scenario(s):

1. You look at your bike and think, what would I do if I could redo it all? Tear it down and rebuild to my heart’s desire.

2. You made an impulse purchase of an SR400 frame and start wondering how you can make this beast look good!


The Idea:

The image below shows the main idea behind what an app/website would look like on an iPad. A simple interface for big man hands to drag and drop the parts to the rotatable display area.

You add a frame of your choice from the selection to the right, then start adding the other bits like an engine, wheels, exhausts etc. Maybe even add some ‘anchor points’ to a frame which should allow the user to stretch out some bits like the suspension, seat area, swing arm etc.

This virtual ideal bike does not have to be real, it does not need to run, it just needs to fulfill the user’s vision of what a build could look like. How about adding a Kitana engine to a monkey or posty bike? Or add Harley wheels to Kawa?

Here it is (click on image to see it in all it’s drawn glory)


Needless to say the app would have some proper 3D graphics and not pencil drawings as you see here. Below is another image with some description bits to confuse you even more explain what all the bits are for.

For example the wheel in the air is an action shot of a part being dragged and dropped in the right place. Granted that it should fail because you probably need forks to act as anchor points before you can connect a wheel up.


Lastly I have to give credit to a site that gave me the idea.

It has some nice features like select from a wide variety, but it is an old school 2D website. And there is no ability to drop suspension, stretch or shorten frame. What about rotating parts I.e rotate the muffler upwards or straighten it out?

But a good start none the less.



Good video, great sound track

Go Pro videos are known for their sturdiness and the users’ willingness to put themselves in awkward positions/situations to get that few seconds or minutes of fame and airtime.

The video below shows a dude trying to cross a flash flood on a bike, but it doesn’t quite work out. Take a look. It is a pretty good clip (ad maybe?).

Not quite sure about the “Be a hero” tag line for this clip. But the best bit I think is the music used. A song called Evil Ways. It can be found here:

The evolution of a custom bike

Not too long ago I bought as an old (’99) VN800 cruiser with the idea to chop and change it a bit into a bobber. It was a good looking bike to start off with but it had seen better days with some sea air rust.

Here is a before:

So I started the build with some minor changes including the rear fender, seat, bars and mirrors.
The interim would result in something along these lines:

The old bike stayed this way until a bit of a head clash with the NSW authorities at which point it was reverted to stock state.

After saving enough spare cash, which included robbing two bottle stores and grabbing at least three old ladies purses, I took the bike to Evolution Motorsports to finish it up to close to legal. And here be the results:


Cafe Racers – The easy custom bike to suite your lifestyle

I love bikes, there is no question about it. Especially the custom ones. I have a custom bike of my own and I have a close to stock bike. I love them both.

Non of them however are cafe racers. A Cafe Racer is a different kind of animal. Small and nimble yet most can achieve a ton up! Drop the bars, throw on a solo seat and cut the fenders to your liking.

Take a look:

Rock the Casbraaaaa SCR ride

This weekend I killed my back on a magnificant ride. We kicked off at The Harbour Hotel and thundered over the bridge!

There were a few bike casualties. But kicking off around 75 bikes and finishing still in the high numbers are always a good result for a group with chopped and changed cafe racers.

Here are some pics and a link to more.

And more…

Bikers, no school like old school

I recently put a post up of an airborne Indian. Today I’ll follow up on that with these tow beauties.

First is old drag racing picture, before the time of major brands and technicoloured drag machines. This is dragging at the purest.

Next is two old blokes going around a track. I would love to know their story. Old friends going around the track one last time?

Airborne Indian

I love bikes, I think I’ve mentioned it before…not sure. But the there is not a lot that calms my nerves than the low thump of a cruiser. Sometimes you see a posed picture with Steve McQueen and you think, ‘Yeah, he’s having fun’. Then you see a picture of an unknown rider doing hill climbs with an old flathead. Awe…

Air Borne Indian

“I carried my camera everywhere in the trunk of my -32 roadster. One day I ran across this guy riding his Indian motorcycle up a steep cliff wall at an old dumpsite in southwest Los angeles.
I couldnt believe what this guy was doing with his heavy flathead indian. He repeted this feat again and again. Thank goodness,because it gave me an opportunity to catch him completly suspended in the air before wrestling his machine back to earth.
One of the main things I remember about this hillclimb was the sound – the roar of his flatheadmotor echoed from the hillside cavern.He would dash up from the pit into the air with his bike, then back down to earth with his flathead motor still popping.
Where is this Indian rider today? He may still be alive today about 80 years old – If, ofcourse he survived stunts like this!”
