Here are some of the details in his words, straight from the builder, Tony:
The motorcycle known as “the viper bike” started as a 2005 boss hoss zz4, model bhc-3 motorcycle.
This bike has been extensively re-designed and re-engineered. It is now equipped with a 2004 dodge comp coupe SRT-10 8.3 ltr V-10 engine with 580hp and 630lb.ft. of torque. The engine is equipped with sequential Multi Point Fuel Injection. The engine is controlled with a Generation 3 JTEC computer system. The generation 3 viper engine has never been offered or sold by Dodge as a stand-alone engine for installation in a non-viper application, So we had to build the entire wiring and electrical system from scratch. The viper engine has only been produced in its history with a manual transmission, so we had to make some changes to make it operate properly with the torque convertor driven automatic trans. We had to design and build a flexplate style flywheel to replace the heavy cast iron clutch style flywheel. This process was complicated because the original flywheel also served as the triggering mechanism for the crank position sensor. We incorporated a reluctor ring into our flexplate flywheel to perfectly duplicate the signal seen by the ECM for crank position information. It has the stock nesco/boss-hoss two speed semi-automatic transmission, which was designed for a Chevrolet engine. We had to build a custom bellhousing to adapt the Viper engine to the boss hoss trans. Parts of the bell housing were made from billet aluminum, and other parts were made from titanium. The aluminum intake plenum and oil pan both required extensive redesigning and reshaping to fit in this application. We thank Ray Shepherd of rays crack repair for his excellent work in the aluminum fabrication on this engine The exhaust headers were hand built from steel, ceramic coated, and the exhaust pipes are 3” stainless steel. All of the body panels, rear cowling, seat body, and hood scoop are hand designed with clay and built from fiberglass in house by Chris from the marine side of our business. It is equipped with custom designed controls by Performance Machine. The brakes are stock boss hoss QTM/Brembo, with the exception of the rear master cylinder being performance machine. The wheels and drive pulley are one-off custom made by R.C. Components at an expense of over $10,000.00 The entire superstructure has been designed around this engine. The rake angle has been increased from 33 degrees to 50 degrees. The bike has a very manageable 4.3” of effective trail. It weighs only 1085 lbs. average fuel economy is 18mpg. The seat is hand made of leather and ostrich hyde, and sits only 23” off the ground. The paint was $6000.00.
Over 1500 man hours have been invested in the production of this bike. Three of us worked non-stop 38 days averaging 14 hrs per day. Most components of this bike were designed by myself as a “finished prototype” and produced to exacting specifications by our in house machinist-Greg Burke, Or Myself-Tony Reynolds. The components not built here, were built off site by John Triplett at Nothing But Customs designs in Taylorsville KY. We are especially proud of johns work in the hidden axle design swing arm. Last year John built one of the very first v-twin bikes with a 360 tire. He builds very well respected v-twin custom pro-street bikes.
Most prototype or concept vehicles are neat to look at, but do not run or operate properly, or are simply “cobbled together” underneath. This concept bike is a finely tuned finished product. There has been an attitude of “cost is not an object” instilled into everyone involved with the designing and production of this bike. According to other non-biased independent motorcycle builders, the bike has an estimated value over $160,000.00
So far, in its short time of being released to view by the public, It has created enormous interest by people in the automotive and motorcycle media. We are now receiving requests from clients to build other exotics that no one else has, even a request for a diesel powered trike!
The Viper Bike we took an order for in scottsdale will be similiar to this one except: a full compliment of gauges frenched into the ram-air hoodscoop, the rear tail section will be for 2-up riding, the engine will have somemore chrome and gloss black, and it will have chrome heatshields on the headers.
(By the way, he is now running nitrous on this one)
