Relocation

Blinkers on the Move

– a quick alteration to shift the indicators from their lower, and exposed, position to a placement just off the headlight. The old location is replaced with a small flush Union Flag motif LED light. Kit made by Terry Harrison in the UK.

Creative Cyclery

Captain Custom

– here is a selection of one-off builds based on the Hinckley twin. Whether it’s a tracker, military hack, cafe or desert sled one of these examples is sure to tickle your fancy.

Woof!

Knuckle Dusting

– the new reinforced hand-guards are now affixed to the Tiger. Australian made Barkbusters have a hefty aluminum strap across the knuckles. Still good wind breaking shields too.

Eye of the Tiger

A Beak in the Wind

The nose of the Tiger might be unliked by some with its proboscis protruding from the eye-like headlights; but I find it offers a strong moto statement aiming for the road ahead.

Repair 101

Duct Tape

– Moon River fender fix. The fine dust kicks up under spirited acceleration as the Apollo 17 astronauts venture up the slope of Taurus-Littrow valley in search of geological samples. Gene Cernan and Harrison Schmidt were the last people to venture past low earth orbit nearly 48 years ago. A damaged fender was repaired by taping moon maps together and clamping them across the mesh tires.

Invention

Science & Technology

– the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. This publication has been in circulation for nearly 150 years so undoubtedly there has been various suggestions for the improvement of motorcycles. The tracked adventure bike looks particularly intriguing.

Lord of the Rings

Pioneer 11

– on this day in 1979 a NASA probe became the first to encounter Saturn and its impressive rings. A gold anodized aluminum plaque designed by Carl Sagan, was attached to the robots body in case in some distant future should it be intercepted by some alien intelligence its graphics may explain its origins. We’ll be long gone by then… but at least in some far flung corner a little hint of our existence will be drifting about.

Owld Shed

Fox River Valley Fliers

– late summer weather is spot-on today. So a new loop added to the local repertoire. Out along Ogden Ave to Oswego then north along art 25 which follows the Fox River through the historic towns of Aurora, Batavia, Geneva, St Charles, Elgin and Algonquin. Finally turning for home back down the leafy swoops of Gilmer Road from McHenry. This building is a hint of the various levels of decrepit industry that supported the River corridor in the past.

Fox River

Fabyan Windmill

– standing proudly on the east bank of the Fox River near Geneva IL a mid Nineteenth Century Dutch mill offers an historic backdrop to my early morning ride along the Tri-City region between Elgin and Aurora. The all wood structure is fully functional driven from its fabric covered sails. This pre-industrial age technology was a stark contrast to the particle accelerator at nearby Fermilab with its circular Tevatron which runs its circular path around a prairie grassland.

Mini Bike

– someone took it upon themselves to wedge a Triumph twin cylindered engine into a small Honda Monkey pit bike. sure looks like a lot of fun!

I can see yonder…

Upright Stance

– long gone is the day when I wanted my handlebars low in racing pose with clip-one. An agéd back and stiffening hips means I need to have the steering fettled to achieve a straighter searing position. The Tigers bars, though tall, still have me in a slight crouch. So I have fitted these Rox Risers which add 2” to the bar height. Huge difference. I sit tall with a commanding stature on the bike. Easy upgrade for me.

In Orbit

Spaceman

– Major Tom Foale spent 6 months on the International Space Station. Army Air Corps Officer, Astronaut, Britain. His choice of ride is appropriate: 1200 Triumph Scramble. Boxed adventure.

Technical Lines

Rotring

– some nice old engineering elevations and plans of a few of the cars built by Triumph in the seventies. I can envision the rows of draughting tables with sheets of vellum and tall stools.
