Stories
Live, high-value sources only. Unique facts are those stated on that page. Factory history is the narrative source; numbers that conflict across outlets are not reconciled here. Vintage Magpul pieces on X @the4t7 (Masada Q&A, PDR, ACR) belong on the vintage page, not here.
Same-week SHOT Show 2010 note — the first dated public mention found. Magpul kept the fuel body, engine, swing arm and frame, and added a four-bar linkage, mono-shock, airbox, radiator and running-light accents. Pointed readers to MagpulRonin.com.
Read at Soldier Systems Daily →Earliest motorcycle-press photo post of the girder concept. Little spec; “no definite plans” for parts. The March follow-up refers back to this January piece.
Read at The Kneeslider →Cited by The Firearm Blog (23 March 2010) and a later recap as the most complete early feature, with photos credited “Isaac.” HFL was later acquired by RideApart. The original article URL was not recovered live or on the Wayback Machine. Treat as a known-missing primary press piece.
Pointer to the missing Hell for Leather piece. Unique restatement: Magpul had “about 25” 1125Rs and might convert customer bikes; would rather be a motorcycle maker than an aftermarket-parts house. Photos © Isaac.
Read at The Firearm Blog →Prints a Magpul release sent by Grady Barfoot. Linkage fork mimics the stock axle path with more trail; single front radiator vs dual side radiators; Motogadget gauge; factory key and steering lock still on the concept; claimed ~50 lb loss. Later production bikes dropped the visible key for RFID.
Read at The Kneeslider →Best early engineering interview with Mike Mayberry. Girder penned and riding in two months; FEA and lost-wax aluminum casting; Penske fork with radiator about the same weight as stock; claimed 413 lb wet. “About 30” 1125s bought — a number that conflicts with later 47/50 counts.
Read at Cycle World →Names each bike after a samurai; first 10 mid-2013, black/silver, from $38,000. The mid-2013 / first-10 claim is later contradicted by factory 2014 production of 12. Flag as early, slightly wrong announcement copy.
Read at Asphalt & Rubber →First public use of the47.com and roninmotorworks.com found. “Ronin Warrior”; 47 later that year (the date slipped). Comments said the site was still getting up that week.
Read at Soldier Systems Daily →Official build film from the vimeo.com/the47 channel. New Atlas later embedded this as a “beautifully made video.”
Read at Vimeo — Ronin Motorworks →Official trailer. No description text in oEmbed. Same channel as the build film.
Read at Vimeo — Ronin Motorworks →Prints factory history. Unique snapshot of names already claimed (Oishi Yoshikane, Isogai Masahira, Otaka Tadao) and still unsold then (Kimura Sadayuki, Horibe Takeyasu, Mase Masaaki). The printed 47-name list has typos — prefer the archived bike pages.
Read at RECOIL →Closest public restatement of the factory /tech-specs page: overflow in the left fork leg, stacked lamps, +13 mm trail, Penske, radial masters, RFID under the airbox, custom loom and high-efficiency stator, ceramic belly muffler. $38,000 vs $11,695 stock 1125.
Read at Bike EXIF →Same-day companion to Bike EXIF. Overflow in a fork leg; stainless exhaust with aluminum ends; RFID; batch prices. Unique tone: the author had not believed the 2010 “dozen or so” hint.
Read at Jalopnik →First 12 on sale, 5 already sold, black/silver, below cost. Comments from people who sat on a prototype: “Ducati 999” exhaust note; “nimble, but muscular.”
Read at Soldier Systems Daily →46-image gallery plus the Vimeo build embed. 54 lb lighter; sold as art — registration is the buyer’s problem; first 12 sold out at $38k; no conversion kit; limited spares.
Read at New Atlas →Mike Mayberry on camera. The Firearm Blog’s write-up of the same embed restates: 50 1125s bought; first three for testing, remaining 47 for production.
Read at Jay Leno’s Garage →#1 Oishi Yoshio in Heavyweight at the 93rd PPIHC. Two 1190 bikes: the photographed mule is the backup; Newbold races the primary. 185 hp / 102 lb-ft; chain drive (unlike the other 46); MOSPEADA paint.
Read at Jalopnik →Highest-value press: on-the-record Mayberry after The One Motorcycle Show. 50 showroom-new 1125s; a linkage fork had already been designed for the Buell XB but never built; 3:1 rising-rate front; Motogadget M-unit and RFID; Crye Multicam batch planned. Photos Dean Bradshaw.
Read at Jalopnik →Only located magazine-style road test. Angeles Crest Highway; mechanic on a GSX-S750 chase bike. Seat compared to Tuono/KTM; girder motion visible from the bars; “flawless” fueling vs stock Buell complaints. Photos Zach Cohen.
Read at Jalopnik →EBR 1190RX, not 1125. Hand-built by Johnny Schwaig and team; CNC billet fork legs; Brembo; BST carbon wheels; 185 bhp; 375 lb wet. Newbold 2nd fastest motorcycle, only a factory Honda CBR1000RR ahead.
Read at Bike EXIF →Thin duplicate of the Bike EXIF Peak feature (photos courtesy Bike EXIF). Repeats 185 hp, 375 lb wet, first-time Peak, The Ride: 2nd Gear. Included because it is a live, dated reprint.
Read at Petrolicious →Eight-year arc from Magpul design exercise to Denver RMW; seven sets over three years; final “art bikes” by Denver artists. Unique mainly for the January 2017 snapshot: #5 still for sale, acid-etched by Jason Thielke, price on request.
Read at Robb Report →Best public equipment checklist for a production bike: 1,125 cc Rotax Helicon, six-speed, belt, girder, Penske F/R, RFID, ceramic exhaust. Ohio title as 2009 Buell; 1,700 miles; Schwaig pre-sale service. Offered from Colorado.
Read at Bring a Trailer →Not listed on purpose: The Drive and Motorcyclist — no Magpul Ronin 47 article was located. ICON Motosports’ “Magpul Ronin 1200” is ICON’s marketing name for an aftermarket one-off, not a factory model and not the RMW1200 document code. Hell for Leather 2010 is flagged above as known-missing. Official social: @the4t7 · the47.com.
