Honda CBX1000 – today's random ad, July 14

It's all about that giant straight-six air-cooled engine. Or at least it was for this wonderful (circa 1978-79) German market ad for the mighty Honda CBX1000. With 24 valves and six carburettors, it was a stand-out techno-beast when launched.

However it was never a great commercial success for the company.

There were effectively two generations – naked dual rear shock and faired monoshock – across several variants.

See the Classic Two Wheels period test of the original

Remote buying & selling – Sunday shed wrap, July 13

Actually eyeballing a bike or test-riding it before purchase has become a rarity at Chateau Guido. Is that a good thing? See the story, here.

Great Eight – the Drysdale experiment, July 12

Australian engineer Ian Drysdale is the ground-breaking developer of a V8 road bike that, sadly, never quite hit the point of going into production.

Now, 28 years down the road, he chats about the experience.

The full taco, July 11

Today we were reminded of why specialist publishers and writers should avoid artificial intelligence (AI). One of the least sexy jobs in this game is transcribing audio interviews, as it requires a lot of stopping and starting and seems to take ages.

So we flicked a file to a highly-rated online AI transcription service to see how it would go. Much of it was pretty good, but you of course miss the emphasis and meaningful pauses in the conversation which can greatly alter how you write the story.

Then there was the detail. I deliberately chose an interview with someone who has a strong voice and very good diction. However when he said "Bultaco" it transcribed as "full taco". I guess that means we're back to doing things the old-fashioned way.

Looking on the bright side, it's given us a new motorcycling term: going the full taco!

See the Cycle World summary of the 1964 Bultaco line-up.

Easy Trails part 1, July 10

We picked up part one of our easy trails project today, namely the 1999 Yamaha XT225. Over the years it's been sold as the Yamaha Serow, XT225 and now the XT250 – all much the same bike.

For a very reasonable Au$2490 (US$1600, GB£1200), we picked up a clean and completely functional motorcycle. We need to replace the mildly bent front brake lever and give it a service – otherwise it's a low-mile happy camper ready for club plates in Vic.

More to come...

An individual dream, July10

The Harley City Collection launched a two-part profile in book form last weekend, from its spectacular facility on the outskirts of Castlemaine, Victoria (Australia).

The unique assemblage honours big dreams, along with ambitious modifiers, tuners and racers from many decades ago and some of whom might otherwise be forgotten. It's a fascinating historic community of fast souls. See the story here

Simplicity for the military, July 8

We evidently have something in common with the Swedish military – that is a taste for light and simple trail bikes, such as Yamaha's 'old-school' air-cooled XT250 (actually a rebadged 225). That country's army has just ordered 1000 of them. The model is no longer available in Australia, as there is no ABS version.

However we recently added a used one, plus an SL230 Honda, to the home fleet. See our latest Sunday shed wrap.

Vincent variants at auction, July 3

If you're into one-off builds with a Vincent theme, these two machines listed for an upcoming H and H auction in the UK will appeal.

The first is what's billed as a 1969 Egli Vincent in typical cafe racer style, carrying an auction estimate of Au$58-66,000 (US$38-44,000, GB£28-32,000). See it here.

Next is a Norvin, nominally listed as 1968, with what looks to be a high-spec chassis. It's carrying an estimate of Au$54-60,000 (US$36-40,000, GB£26-29,000). See it here

Which one would you choose?
