1987 250R/350X - Update Dec 2014: 1987 250R-H Parts Catalog Located *Pics!*

What is the significance of the 87 cylinder? I have one freshly warmed over from Jason Hall that has HA2 and 87 stamped in the sleeve that came from a TRX250r? What makes it possibly an 87 ATC cylinder?

ha2 is the honda parts code for atc250r, hb9 i think is the parts code for trx250r

Right. HA2 Is Specific to the ATC 250R.

HB9 is the TRX250R product/Parts code

According to the "Man" the 87 R cylinders had more aggressive porting, and from what I gather elsewhere slightly larger intake volume vs any other year.

we use the "88" CR Cage with Boyesen Reeds,Honda Part No. 14100-KS7-831
and the "87" Cyl. was the First Long Rod Set up... the Porting is NICE !!

Queso I have a cylinder I will take pictures of tonight. I bought this cylinder a number of years ago from EBAY.

Very cool, thanks for the information Mosh!! I bought the cylinder I am referring to on Ronnies recommendation and it was at his shop for him to warm over. I got it back from Nathan and last year at the Invasion I spoke with Jason Hall and he agreed to warm it over and engrave "Yamahondaman" on the side. Got is last week and it looks dynamite. As promised pics tonight.

IMO, Ronnie and Jason may know(n) the R's more than anyone else out there for squeezing stupid power from stock configurations.

[Mr. Clean]

Pics as promised. I reserve my judgement as this being an ATC cylinder versus TRX, the previous owner told me it came from an 87 TRX to be replaced with big bore cylinder.

[Billy Golightly]

Yes, Ronnie always liked the 87 cylinders the best, one of the things he pointed out to me is the ribs in the transfer tunnels were shaped differently than other years.

In the grand scheme of things, I have no doubt Honda recycled some of these ATC parts onto TRX's, since it was right in the time frame when everything was going belly up. This makes the I think its 3rd one I've seen before now with the ATC product code and then the 87 year stamp.

It makes me wonder just how much of the TRX stuff would have made it into the ATC really.

But, just like much of a given model years production actually takes place the calendar year prior, wouldn't it be safe to assume parts catalogs would be printed well in advance also???

Interesting material for sure Slash.. But in my mind it doesn't equate to a certainty of actual '87 model year trikes being out there...

Any developments on that title you posted a pic of awhile back???

VIN's will be the ultimate proof...

[El Camexican]

Don't ya just love those classic Canadian reflectors on every model? I wonder how many millions of lives they've saved over the years


Good leg work Slash, don't give up, it could still happen.. Last year while up North I asked around to some of my buddies if they still had any 1987 Honda brochures or a recollection of the 87 and none could find or remember one, but at least 3 of them recalled seeing a sasquatch that year.

[Darius1502]

Between Mike and John if anyone can find some '87 parts or a full '87 bike its these guys!! We are in great hands!! Nice work gentlemen!!

[Buster Brown]

I have the microfiche that includes the '87 ATC 250R. Don't have a reader machine, but I'm looking into digitizing the fiche to file. Still doesn't mean any were actually built...?? I kinda think it would be interesting to see all the updates and part numbers. Like the '87 airbox, it received a resonator tube (bottle) to lessen intake noise levels similar to the TRX in '87.

[slashfan7964]

Mike said he "thinks he might of found Sasquatch." Stay tuned, I'm digging for information.

$50,000 reward to anyone who can prove the 1987 250R exists. There's some interesting comments from a former Honda employee who says they did indeed sell them.

This would line up with what Honda Canada told me over the phone.
