Further thoughts: Let’s see, didn’t WSB just decide to up their displacement limit for V-Twins to 1200cc? So Ducati could race, right?

Detonator Fantasy Concept Motorcycle by Daniel Simon

Detonator concept motorcycle design by Daniel Simon

A question in the comments about one of the ads on The Kneeslider brings us to this fantasy concept motorcycle. It’s called the Detonator and it is the work of Daniel Simon. As pointed out on his website, there is no intention of this being a functional motorcycle, it was just a design produced by combining basic shapes like cubes and cylinders.

Some of you, who are adept at using the advanced 3D design software available these days, may find nothing remarkable about this bike or his other designs but I find this sort of thing really creative. He has quite a display on his site covering lots of different subject material.

He has a background as an intern with Lamboghini and then work for both Bugatti and VW. Quite a capable fellow. He has a book, Cosmic Motorscoming out soon, too. If you like design ideas, you might want to check out his site, I think it’s well worth the time.

Formula Bike - 125cc Entry Level Racing

Formula Bike by Marilley Motorsports

Formula Bike by Marilley MotorsportsA Swiss company, Marilley Motosport, has designed and built a 125cc entry level racer called the Formula Bike. Its purpose is to give young racers the chance to prepare for racing in the higher level classes and also to be a very accessible level of racing for the non professional. The initial version is a 40+ horsepower 2 stroke available in March of 2008 eventually to be transitioned to a 4 stroke by 2010.

The Formula Bike sports 14 inch wheels front and rear on a tube frame with an aluminum swingarm. Price is quoted as 8500 Euros.

There seems to be growing interest in small displacement motorcycles at reasonable prices for entry level racing, something less costly and more manageable than jumping on to a 120+ horsepower 600cc racer. The formula bike is similar in concept to the 450cc dirt bike based racer from Gavin Trippe.

The company is working to organize a Formula Bike World Cup series to showcase these bikes and the racers who ride them.

2008 Bimota Tesi 3D Fresh off the Boat

2008 Bimota Tesi 3D

The Italian Bimota is a brand of motorcycles that are out of reach for most of us. This, of course, makes them highly desirable for most of us. Getting a first look at the all-new ’08 Tesi 3D at the Barber Museum on Friday was definitely the highlight of my week. Every now and then I happen to be there at the right time, and get a glimpse of something spectacular. Two months ago I saw Barber’s technicians tear apart the #7 Britten V1000. Sorry, forgot my camera that day.

2008 Bimota Tesi 3D

The latest addition to the collection, the new Tesi 3D arrived Friday and was uncrated just a few hours before I saw it. It will immediately go on display, probably next to Barber’s original Tesi1D prototype. Its new permanent home will make a nice homage to Pierluigi Marconi’s “thesis” project, and it will never be run. Incidentally, if you ask an Italian, “Tesi” is pronounced “tay-z”. I stand corrected!

Since the floor plan is so open at the Barber, I spotted the machine even before I could get near it. And as I got closer and closer, it was almost certainly glowing. I swear I heard a few angels echoing in the background. With floors so clean you could lick them, the bike looked right at home.

2008 Bimota Tesi 3D

This Tesi, apparently number 15 out of only 29 numbered bikes to be built, weighs in at 370lbs. It’s powered by the Ducati 1100DS motor used in the Multistrada and Hypermotard. And, although it feels tiny between your legs, I mean really tiny, it fits like a glove. Most bikes are far too wide in that area. Even with its 31.5” seat height, the skinny waist let my feet stay flat on the ground. And that’s with the bike still on the rear stand!

2008 Bimota Tesi 3DI must have gawked at it for over an hour. I thought to myself, this may be the closest I’ll ever be so I better make the most of it. I was truly impressed with how “finished” the bike looked, complete with charcoal canisters, California emissions stickers, and safety reflectors. This is a well engineered production bike. Even with the controversial front end, I still want one.

This brings me to that controversial front end: the hub-center steered swing arm front suspension which Bimota has been perfecting since the late 80’s. And, like the 1920’s Ner-a-Car, hub-center steering on a bike is nothing new. It works. This version looks amazingly simple up close. It even looks like they’ve added a few degrees to the rake since the Tesi 2D. The 3-piece billet alloy, hub/caliper mount has a large diameter to allow maximum wheel pivot on the center king pin. The carbon fiber linkage rods were a nice touch, too.

2008 Bimota Tesi 3D steering close up

2008 Bimota Tesi 3D steering close upThe front end is suspended by a nicely integrated, pull-rod, air/hydraulic monoshock. This should give the forged aluminum wheel over 4in of travel, with tie-rods keeping the king pin at a constant angle through its travel. You won’t feel any dive during braking on this setup. Anti-dive is inherent to swing arm front suspensions because the brake force transfers in a more direct line to the chassis Center of Gravity.

Probably one of the nicest design features of the new Tesi 3D, is the way it combines tubular steel with billet aluminum. In particular, I like how the converging lines of the rear swing arm terminate at the beautifully machined alloy axle stays. First shown on Bimota’s DB5, this style of assembly is truly innovative and beautiful at the same time. It’s the best of both worlds, in my mind: simple welded steel trellis mated to high-precision, light weight alloy drop-outs.

I can only imagine what it would feel like to ride this remarkable design. Within view of a pristine asphalt track only 100 yards from where I’m standing, this was starting to feel like some sort of torture. All I could do was close my eyes, make some annoying revving sounds with my mouth, and imagine flicking the thing around the track. At around $36k, it seems like a bargain for the level of engineering and craftsmanship you get. I think the Bimota name alone could warrant a higher price. I mean, do you know anyone who owns one? I’ll leave you with a few more pictures:

2008 Ducati 848

2008 Ducati 848

Ducati has introduced their 2008 lineup and the 2008 Ducati 848 breaks cover with a 134 horsepower engine in a 369 pound package, giving the 848 a better power to weight ratio than the 999. Looks like a nice addition to their middleweight models.

From Ducati:

The words ‘agile’ and ‘refined’ aptly describe the 848. At 168 kg (369 lbs) the 848 is an amazing 20 kg (44 lbs) lighter than its predecessor, and a significant 5 kg (11 lbs) lighter than its larger capacity brother, the 1098.

The highly advanced 848 engine uses an improved method of engine case production in which cases are vacuum die-cast formed. While providing significant weight savings of more than 3 kg (6.5 lbs), this method also ensures consistent wall thickness and increased strength. Further refinements include a sophisticated wet clutch that offers 1 kg (2.2 lbs) less weight, a much higher service life, improved clutch feel and quiet operation.

Hayabusa V8 for the DP1

Hayabusa V8 in a Lotus 7
It’s been a while since doing any updates on Dennis Palatov’s DP1 project so I thought I would stop by and see what’s up. Wow. If you’re not familiar with the DP1, it’s a track car designed and built by Dennis Palatov with a carbon fiber body and a Suzuki Hayabusa engine. Extremely high end design work and engineering involved here, and he’s going to produce them for sale, too.

Hayabusa V8Since checking in last, it looks like he’s entertaining the idea of using a Hayabusa V8 and a transmission of his own design. The Hayabusa V8 has been a very popular post here and I know a lot of folks keep speculating about what it would be like in various cars other than the Radical SR8 for which it was originally designed. The photo above shows one running in a Lotus 7. Is that sweet?

Here’s another photo of the V8 from Dennis’ site but you really need to go there and check out his work because he’s been a very busy guy and there’s an alternate design submitted for his car to check out along with progress on the DP1 as originally designed. This is first class work of the highest order and I am definitely impressed.

Projects like these just amaze me. The skill involved, unbelievable.

I can’t wait to see the finished DP1, but in the meantime, I think I’ll just stare at the engine photos. Gawd!

Another thought, why don’t some of those guys who insist on stuffing Chevy V8s into those oversized monstrosities try a Hayabusa V8 instead. That’s a far more elegant design from an engineering standpoint and the bike wouldn’t have to look like an elephant. Just a thought.

Husqvarna wins the enduro and French motocross

Thomas Allier

After 25 years Husqvarna has returned to win a race in the French motocross championship thanks to the fantastic performance of Thomas Allier in the first round of the transalpine championship taking place in Villevielle, southern France.

Allier, riding the Husqvarna TC450, comanded the MX1, winning the first round, obtaining third place in the second and a victory in the final round where he also won in the MX2 class. C. Martin, the second rider of Team SIMA also did well, coming in fourth and third. Allier therefore heads up the MX1 French championship and C. Martin is in sixth place.

In the first series of the French enduro championship at Cosne sur Loire, the E3 class enduro was won by Guillame with less than a second’s difference. Guillame with the TE 510 came in before Namboten, racing with the 300 two-stroke. Second place in the E1 class was won by Marc Bourgeois behind the winner, Julien Gauthier. Husqvarna leads the manufacturers’ ranking.
