1986 Honda ATC350X Show Trike

Filed under: Bikes, Trikes, ATVs — Nicholas Fluhart @ 7:41 pm

In keeping with the ATC (All Terrain Cycle) theme, I thought I’d post a bike I sold a while back: a 1986 Honda 350X. This was a restoration project completed in the late 90’s by some friends of mine, and only OEM Genuine Honda parts were used from the tires up. Today most of those parts are discontinued and virtually impossible to find. Now, if you are a true Honda nut, you will see that there are four parts that are not OEM which I will address below, but in the mean time see if you can identify them…

This might be the cleanest 350X you’ll find short of building a time machine and traveling back to 1986 (something I dream about frequently). I’ll provide a loose rundown of what was done to it.

First, the bike was completely stripped down to the frame. All components were sandblasted and then powder coated, such as the frame, foot pegs, kick starter, swing arm, hubs, etc. A new OEM exhaust system was stripped and then JetHot coated. A new OEM heat shield was coated and installed on the header. All bolt-on parts, i.e. air box, lights, plastics, switches, cables, etc., were replaced with brand new OEM genuine Honda parts. Even the rims and tires were purchased from Honda and are period correct to the 1986 model.

On to the engine: When three-wheelers were discontinued in the 80’s, dealers received monetary compensation from the manufactures for existing inventory, but the physical machines were dismantled and scrapped. However, several engines survived as the dealers donated many of them to small-engine vocational schools. Many of these engines, although there are much fewer today, are still around and untouched. They are commonly referred to as “crate engines”. Through my moderately extensive contacts in the industry, I was blessed enough to have obtained a few of these priceless jewels, one ATC250R engine and a couple of ATC350X engines. One of my 350X engines found its way into my TRX350XX conversion bike. These guys got their hands on a couple of them as well, and one was used in this trike. It was repainted with high temp paint and clear coating, and there were some parts that were polished and cleared.

Here are some closeups of the trike:

Now, were you able to identify the 4 aftermarket parts? Well, to a true Honda enthusiast it should have been fairly easy. Up on the handlebars you’ll note the clutch lever is an aftermarket upgrade (1), and since it doesn’t facilitate a parking brake cable, you’ll notice the parking brake blockoff on the rear brake caliper (2). And also at the rear end, you’ll see the machine has a stance that is much wider than factory, and that is due to the upgraded rear axle which is a Dura Blue plus-5 extended axle (3). And finally while your looking at the rear view, you’ll note the word “Ceet” on the back of the seat. Ceet is the leading brand of aftermarket seat covers (4).

The guys did three ATC350X restoration projects simultaneously, and one even turned out better than this one (I know….that’s hard to believe). I don’t know the overall cost of the build, but I sold this trike to a collector for almost one thousand dollars more than the bike’s original MSRP. What’s also astounding is that an original, unrestored bike in this condition will bring even more. The ultra-clean ATC’s from the 80’s have now officially reached collector status.

  1. I can’t believe the condition of the rear fendor. I’ve have an 86 that’s in fine condition but mine don’t look like that. Are there any original parts to still get? Especially the tank warning stickers and a headlight guard? That thing is sweet!

    • Thanks for the comment. Most of Honda’s OEM parts for this trike were discontinued in the late 90’s, but there are still a few things left. You may try or a similar site for OEM parts.

  2. Fantastic restoration! I personally started with a 85 kawasaki klt 160 then got my hands on a 83 200x and a 250sx. Shame on the people who didnt learn to ride them first then play. The tri’s were fine bikes and fun to ride. Quads are so boring.

  3. I have a 1985 350x all stock that looks as nice as this one and may have less than 15 hours on it. It was made in Japan. The serial ending in 008411. I would like to sale it.
