DCR-018 Billet Sting - rNineT / DNA High Performance Filters




The Nick Name

Our Dream Bike, the DCR-018 has a nick name that you already have seen in the title of the press release. The Honeycomb design, the billet aluminum that dominates, and the aggressive style of this unique and ‘nasty’ fast Boxer racer, is what inspired us to come up with “The Billet Sting” nickname and the awesome Wasp Logo!





The style

Mario grew up playing with the Monocoque 80cc racer, inspired by the ‘strange’ but awesome frame design, came up with the idea, to design and build a modern racer inspired by the almost 30 years old design! Crazy idea….but what if it could get even crazier? The ingredient to transform a ‘crazy’ idea to a design completely “out of the box”, was to add the so popular BMW R9T engine!







The Forced Air Intake

Key component of the bike’s design is the forced air intake. The intake is designed in such a way to serve as 2 hexagonal tubes, that channel the high-speed moving air to the DNA Filters, and at the same time acts as a structural part that supports the fairing windshield and double front LED lights. Extremely complicated parts, CNC machined from huge blocks of 6082 alloy to a final section of 1.6mm thickness and 600mm length! The profile of the tubes is a slightly modified Honeycomb, as minimal as possible, with no visible bolts or welds! Designed to provide a constant positive pressure increase, at speeds above 160 km/h, and zero restriction at lower speeds! The air filters used are 2 large 66mm DNA Blue Leather Top Reddot Design Awarded Pod filters! Filters are caged in transparent Lexan airboxes, with the BLUE Leather top protruding! The filters are connected to the throttle bodies via 2 huge 60mm ‘Hand welded titanium’ runners, following the contour of the frame. The forced intake is designed to increase the VE (Volumetric Efficiency) of the engine at high speed, and it definitely works!

The Engine

The BMW R9T 1200 Boxer engine that powers our ‘Billet Sting’ is the latest air/oil cooled engine BMW produces. With a 1.170 cc capacity and Radial 4 Valve heads it is rated 122 whp @7.900 rpm & 12.3 KGM @6.200 rpm with a final Power to Weight Ratio of 0.66 whp / kg.







The Instrument

Starting from the front the frame incorporates, the steering head roller bearings, the multifunctional Display/telemetry controller SDM 550 made by PLEX-TUNING.COM specifically for the DCR-018! The 5 inch display with a viewing angle of -80 to +80 degrees (top, bottom & left, right) from vertical, with 800 CD brightness and a day/night sensor, LCD & LED rev meter & shifter lights, fully Can Bus is just a beauty!


 

The Frame

A Monocoque Aluminum frame design. Consists of 10 different parts CNC machined from 6082 T651 alloy. The parts are welded together and key geometry details are machined post welding. The frame is machined in a ‘Honeycomb’ structure, in order to reduce weight without compromising strength. Additionally, it is the visual ‘skin’ of the bike! The machine tool paths are visible, no plastic or synthetic covers were used! The final frame is clear anodized in order to be protected against oxidation. You can see and feel the bare metal that is so sexy! Starting from the front the frame incorporates, the steering head roller bearings, the multifunctional Display/telemetry controller SDM 550 made by PLEX-Tuning specifically for the DCR-018! The 5 inch display with a viewing angle of -80 to +80 degrees (top, bottom & left, right) from vertical, with 800 CD brightness and a day/night sensor, LCD & LED rev meter & shifter lights, fully Can Bus is just a beauty! Under the display is a huge Lithium Ion battery that weighs only 840 gr! And under the battery the car style alternator. In the mid-section of the frame you can find all the engine management units and the wire loom. The fuel tank/fuel pump is installed at the rear section of the frame, just over the rear shock top base. Last but not least the top cover of the frame, that is also a structural part.




The rear Frame/Seat

Monocoque Honeycomb design continues. The seat is also a structural part, no tubes or other hidden parts. It is seamlessly connected (bolted) to the front frame. The central part of the seat is designed to open and locks in place with a titanium quick release connector which can be operated via bare hands. Once opening the seat you can find the main switch that powers up the beast, with the ‘D’ KEY which also opens the fuel tank. Inside the seat neatly sits also the base of the exhaust mufflers! At the rear, incorporated in the design, is the Double Honeycomb rear light, all CNC machined minimal and features latest LED technology. The design of the rear light mimics the huge Double Honeycomb intake in the front of the bike! Seat cushioning is designed in 3 parts. The middle part opens with seat, and the upholstery is synthetic non-slip leather? light blue color. On the seat facing forward is the logo/nickname of the bike laser engraved. ‘The Billet Sting’
