Kanai unearths 15 year-old ‘low profile’ cooling head prototype


Perhaps in a thinly-veiled ‘I was there first’ response to this morning’s rather ‘high profile’ release of OS’ new ‘low profile’ B2102 engine, Yuichi Kanai posted his own take of the low profile design, albeit 15 years ago when he was World Champion with RB.

Despite getting it made and anodized his signature green colour, Kanai revealed it remained only in prototype form, never taking it any stage further, which we thank him for as it’s not exactly going to make the cover of Vogue magazine anytime soon…

O.S. unveil new ‘Low Profile’ B2102 engine

Originally spotted on Facebook from the Tokyo Hobby Show was this brand new development from O.S. Engines under their high performance ‘O.S. Speed’ brand.

The new B2102 engine boasts a very striking ‘low profile’ cooling head – going against the grain of convention which traditionally feature much taller alu cooling heads to take advantage of air flow to regulate the engine temperature.

O.S. tell us the engine also has a new carburettor which improves fuel mileage; “Ten-minute driving per fuel tank is not privilege of throttle sensitive top drivers any longer but for everybody now.”

“The new low-profile cooling head makes buggy’s centre of gravity much lower (-17 mm), which improves car handling drastically without sacrificing cooling performance.  Car handling at corner is improved a lot.  New experience.”

The engine will be available to the public from December 2016, no less than the carburetor, crankshaft, crankcase, inner head, outer head all newly developed parts.

Continue reading below for a quick analysis of the new head and why the engine is only 5 grams lighter than the B2101 and 7g lighter than the XZ-B Spec II.

Rody Roem returns: announces Victosport VSB01 Engine


Rody Roem, a name some of our younger readers may not be too familiar with, however a quick history lesson – universally known as one of the best ‘engine men’ in his day, leading his company RB Products to several World Championships, has teamed up with O.S. Engines of Japan to announce his first Offroad engine, under the brand VICTOSPORT.

Loosely based on the rather brilliant OS 21XZ-B engine, Rody tells us the main differences aren’t only a different badge and cooling head but include –

The use of my own made combustion chamber and my own newly designed Bi-Turbo crankshaft. Together with a specific timing this engine puts out a linear power and competitive fuel consumption.

Intended for ‘experienced’ users in high competition, the VSB01 engine is a 3 port long stroke with 14mm Bi-Turbo crankshaft, balanced, lightened and silicone paste,’Rody’.
