Yet more Macau GP...

I seem to have a good amount of HRC Endurance photographs, ironically I've never owned a Honda motorbike...
Some additional Moriwaki photographs...
Umm-hmm, by this point you should all know how much I like the Moriwaki brand, machines, legacy, and livery. Here is some more goodness...

Norvin
Some beautiful construction and machining on this Norvin here. I do like the unique older motorbikes like this (or similar such as a Seeley Matchless), I am not so much a fan of just box stock mass production OEM restorations (e.g. concours resto CB's or RD's -sorry, you won't find too many of them here!).

There is some great reading, diagrams, and photographs at this blog. Looking forward to analysis of Monaco. No point in me re-posting all of the photographs, please give them the traffic and click around taking a look yourself (link is below).
Great shot of a low tech solution on a high tech piece of racing machinery:

Even more Honda Endurance views...
Some of these photographs are credit to Honda Racing, the top view of the tank is shown here elsewhere as well, but it's so awesome a piece of kit it deserves to be reposted.

Suzuki-Bimota SB1 500
Rarely do I run across photographs or articles on this machine - similar Yamaha's and even the Kawasaki's seem to be more common. I find it quite interesting how minimal some of the bodywork was on Grand Prix type machines of this era, then how bulbous bodywork became especially on production motorbikes (e.g. SRAD tail sections), only to have a return to stubby tails and narrow profiles...

Team Rumi RM701 SoS Racer
Now this is hot. I have been into racing motorbikes for quite some time and this is the first I have run across this. I have definitely seen the Rotax engined/TZ250 chassis conversions from the shop in Colorado that race in US series but I guess I am just not as familiar with the European SoS series as I thought I would be. Enjoy.
Excerpt from the Rumi website:
To modìfy thè air-cooled NX650 sohc four-valve engine, measur-ing 644cc in stock form with its 110 x 82 mm dimensions, Rumi en-listed thè services of Carlo Facetti. He’s one of Italy’s top development engineers and a noted name in FI racing car circles after his work designing FI race engines for Alfa Romeo and, just recently, Lamborghini.
Facetti already works on thè Rumi Honda Superbike motors alongside another freelance engineer from thè racing car world Ernesto Degan - formerly a designer for Alfa’s Autodelta racing subsidiary who’s used to adapting produetion engines for racing.
Facetti completely revamped thè top end of thè NX650 motor, retaining thè crank-cases, wet clutch and five-speed gearbox from thè stock Dommie engine, but convert-ing thè air-cooled engine to water-cooling and replacing thè radial-valye sohe top end with Degan’s dohc design with paired valves. The originai chain drive to thè cylinder head is retained, but instead of turnìng thè originai Honda camshaft, it now drives a half-tìme pin-ion, outboard of which is thè waterpump and inboard a gear wheel meshing directly with thè twin overhead Rumi camshafts. Twin 43mm inlet valves and 35mm exhausts are fitted, with a fiat included l-just 26.5 degrees. At present, though . gìne was designed to run on fuel ir and has already been dyno tested guise (using twin Weber injectors ar. ‘ software on a TDD engine managen.-. tem similar to that used by Bimota : own BMW-powered BB1 Superino: prototype racer is running on twir. Keihin flatslides, in which form it deli” bhp at 9,000 rpm on thè Rumi dyno already have 77bhp with EFI, accoro: Norris Farrow.
All thè hardware, including a batte-pump and air duets for a pressurisec needed for EFI are already in piace. the switchover from carbs and th-: Honda CDI presently employed quitt
As well as water-cooling thè engine has also bumped it out to 697cc with ir of a 104mm three-ring Mondìal forge: delivering 10.3:1 compression, and th-gives thè sort of jump out of slow corot thè Mallory liairpin or chicane that thas-riding 550cc ‘Ducatinas’ can only dreac
The engine is unbelieyably punchy when you crack thè throttle wide open, especially at high rpm. Out of a fourth gear corner like thè Mallory Esses you can feel thè front wheel rise lazily in thè air as you get hard on thè gas, confirraed by thè way thè bars jiggle gently in your hands as you monowheel to-wards thè Hairpin cranked hard over.
Exiting a slower turn like thè chicane or hairpin causes quite a bit more excitement if you try to do it in either of thè bottoni two gears. First is actually way too low for racing use, but great for improving your wheelie credit rating with spectators. But get thè Rumi motoring out of a slow turn and it’ll get
a jump on a Ducati that takes a while to peg back, as I discovered for myself riding briefly with Simon in Dundrod qualìfying - untìl an-other minor glitch sent him coasting up thè slip road with a dead engine. Then, at thè other end of thè performance scale, thè Rumi is very fast in a straight line on outright top-end speed, certainly quicker than thè five-valve Yamaha XTZ engine of equivalent capacity, as thè Ulster GP speed trap showed. The Stephens Yamaha that Jim Moodie used to win thè TT was no match for thè Rumi on absolute performance.

Unsure of photograph credit unfortunately, I did find some alternate images on Cafe Racer Team's blog however I am not going to link to that as there is some NSFW content.

This is always a favorite. More information on the Gregor Halenda and Scott Kolb build available on the Team Incomplete Boxer website.

It's a chopper baby....
...that I always thought was from Shinya Kimura, but now am pretty sure that isn'c correct. Help me out and post a comment on the builder if you know.
Note - Thanks to Zach we now know it is from Zero Engineering, the "Junkyard Phantom".

Check it out, I love this thing. Suzuki should take some design cues. Unsure of this particular photograph origin, offical Marcus Moto Design photographs and information here.
