**PLEASE READ THIS IMPORTANT NOTE ABOUT OUR TANKS**
We offer these tanks two ways: Mill finish, smooth planished sanded finish OR Highly show polished, which is a very labor intensive sanding 5 step process before taking it to the buffing department for a two step comprehensive show quality finish.

Neither tank and seat are a direct replacement for your stock units. To achieve this we would have to literally have hundreds of tank bottoms and seat designs to facilitate it.
Instead, we designed a general backbone tunnel "universal design" then make minor modifications to make it fit specific models. I've also found over time that the mounting system with the cup and pucks are not strong enough on the aluminum as they are on the stock tanks. In the case of the CB750 SOHC models for example, require cutouts for frame gussets and recessed areas for the carb slide heads to operate.
 
My mounting system consists of flanges blind nuts welded into the tank bottom whereas you use your own strap iron bracket fastened to the frame then bolted to the tank using the nut locations. INSTRUCTIONS INCLUDED
  Also, normally these tanks are what we refer to as "UNIVERSAL FIT" tanks. That is they are made with a bottom that has a tunnel which will fit the standard single backbone tube frames, Normally most pre- Dual Overhead Cam bikes (circa 1950 to the Late 1970s).
 We will be glad to quote the custom bottom for your application, however there will be an upcharge for this additional service. Should you want the custom fit bottom tank this is considered a custom fit tank and under no circumstance is the tank returnable as it is a one off build for you...
 There may be an additional price adjustment as the checkout does not correctly calculate insurance and international shipping prices or foreign currency exchange fluctuation.

Fabricated from over 1/16" work hardened aluminum Alloy, These tanks are HANDFORMED in the UNITED STATES by old world craftsmen (David Ashenbrener) with pride which keeps the surface unwavering, thickness uniform and unstressed as possible.
 The tooling forms I use assures that they are symmetrical and authentically shaped to their antique counterparts.  All seams are beautifully TIG welded by highly trained Aerospace Professionals, right here in AMERICA.
 These are superior to anything that's coming out of the 3rd world countries  You will be very impressed with our quality and attention to detail.  I hand planish each and every one until perfection is achieved.
 Your Bike is your Persona...Why take a chance...? Do you really want to put a wavy, scratched tank with scabby and leaky welds on your show machine just to save a couple bucks...?
Fabricated of 16ga. 1.65mm thickness Aluminum, these tanks are the exact shape of the original tanks used on the Ducati S2R and S4RS Monsters.  S2R models will accommodate the replacement of your stock fuel pump with the S4RS pump which is readily available and reasonable to acquire (S2R  flanges are available for an upcharge). Tanks are formed to the nomenclature of the original top outer and includes the CNC machined flange, fitted with blind nuts for the EFI fuel pump.
The Mill Finish is appropriate for painting with standard paint prep. Polished finish is also available as an option. The fuel cap well is billet aluminum and is perfect for the wide variety of aftermarket caps available. All seams electrically welded by aerospace qualified personnel.
The tanks feature cast panels employing tapped lugs (Blind nuts) to accept stock hardware (fuel pump, front cam-lock latch and lower grommet mounts). The DOT approved submersible inner lines, facilitate the vent and overflow tubing necessary in keeping with EPA guidelines.

The parts are precisely cut with CNC machines, insuring accuracy and repeatability, making sure the tank is symmetric and clearance is correct from one tank to the next. Our CNC department machines each fuel pump flange and billet fuel cap well to a very high degree of accuracy, insuring the cap matches the top level of the tank with minimal space around the cap. These are details not attainable with hand fabricated parts. The outer tank skin is accurately matched up to a form, literally lifted from the original tank nomenclature.

Rounding up the tank integrity are aluminum components with tapped blind lugs for the cam-lock front mount and lower side grommets. All above parts are done in house and there are no imported components used. I have been fabricating these for over 5 years and they have gone through numerous design improvements.

Recent upgrades include Blind Tapped Holes for mounting the fuel pump, newly designed cap well for perfect fitment of aftermarket caps!
These are usually available for quick delivery however, Call for delivery production schedule.
