ST1100 to STealth11 Project

My other R-Trike is the VALK3


    Well as with most things it started out with an idea which seemed feasible and also financially acceptable. The Honda ST1100     seemed to be a good choice for this project as it has a very unique longitudinal V-4 engine layout, it delivers comparable horsepower to the Can Am Spyder (92hp) but unlike the Can Am is capable of 46-48 mpg (Spyders are in the low 30’s) and the ST comes with shaft drive and all the maintenance free options. For a base I tried to approximate the wheel base and layout of the Can Am along with the basic suspension layout. Other than that it was a plan as you go project full of trial and error. Keeping in mind anything is possible as long as one can melt metal with fire!                   Facts figures and ride reports

Update - 3/8/2012 - Stealth11 is completely stripped down and is getting a facelift. New paint, new square headlight and signals, and many small improvements. Pictures to be added soon......
I found this 1995 unit that was flipped over but did not impact any cars or objects, the plastic was mostly gone but the frame and running gear was 100%. This bike had less than 13k on it so pretty much new.

First order of business was to remove everything off the front of the bike. Wheel, fender, fork tubes, brakes, radiator - everything including the handlebars and engine shrouds.


With angle iron in hand the sub frame began to take shape. Bottom rails set the structure square and determine the length and width of the A frame mountings.


I purchased a front suspension assembly off a Yamaha 700 Banshee four wheeler rather than build my own. This sure made assembly here much easier.


Things are really starting to take shape here. New tank cover, side covers and radiator plus plumbing.  The new plastic will need some work as all this also came from other crashed ST's

Upper control arms in place and spindles added. The shocks are from my 98 Valkyrie but proved to be to weak and were replaced with GL1500 rear coil over shocks.

Steering assembly complete, bracing done and electrics at this point is functional. Ready for not only sheet metal but that first test ride. After a short run only minor adjustment needed. "Success!"

Another view just before I added fenders and remaining trim pieces to front of machine,

 

Memphis Shades windscreen and all the trimmings are complete. Sway bar also added just before sheet metal was added.



Completed project with soft bags. Mirrors mounted to handlebar ends work great and I use a Garmin Nuvi 200 for a speedometer.

After a bit ob "hot wiring" I was able to get her started and it ran just fine. Even though the front wheel and fender etc was fine - it was to come off and go on the eBay sale block in short order.

Here the bike is ready to start adding the front frame assembly. The radiator was removed and was put aside for reinstall later.



A set of "wings" are added purely for looks and to provide more width for added wind deflection and rider protection. At this point the radiator is mounted in it's new permanent location in the forward section.

I used a pair of 11" pipes to replace the stock fork tubes. The triple trees need to stay intact and ridged as this assembly will still be used to transfer steering to the front wheels.


I picked up a pair of 14x6 generic four bolt black rims. Also added an old Yamaha XS11 headlight and old Honda 750 signal lights. Handlebars are generic units found in the salvage yard.
Added wheel adapters to go from 6" centers to 4" bolt patterns. additional trim pieces added also. Caster and camber at this point is to stay as neutral as possible - as a guess.

Sheet metal applied and a few coats of body filler applied. Plastic starting to look better as body work done and first coat of flat black added.


Final pain scheme in keeping with the whole "stealth" idea. The entire machine is painted a satin flat black and the accents are full flat black. If nothing else it's easy to touch up.

Another view of the front complete and new GL shocks installed which turned out to be perfect.
