There have been a couple members wanting to weld in a rear motor mount. The back of the motor has one set of holes which Honda did not use when they revised the frame for 88. So over on FB there is a pic of a frame (not OEM) with two tabs welded on the cross member to bolt the rear motor mount to. Well the OEM frame has a part welded in that place the suspension bolts to. So I cut a tab to weld to the top of that part.

Thats a great idea to go with your gusset kits. I wondered why they never tied that in anyways?

Just an idea, but think about it.
If Honda had put that extra lower mount on the frame, probably wouldnt be, as many upper mount cross over tubes cracked on the new model frames, resulting in some owners replacing the frame altogether, so if they had those extra brackets in place, then replacement frame sells would be down.
Another item, chain guide on the swingarm.
If Honda had put that chain guide in place on the OEM swingarms, probably wouldnt have been as many left hand case halfs sold from the chain flying off, + chain & sprockets bent or teeth missing when the chain balls up between the front sprocket & swingarm.

Other items, grease fitting on the swingarm bolt, on new model swingarms, to lube between the bolt & spacer tube + to lube the bearings as well & a thicker cast OEM cylinder head, so it would hold more coolant & provide better cooling, + being thicker it could be machined on more & still retain its strength & hold its shape better.

A real big one that would have been nice if done, would have been if some cooling fins cast into the rear brake caliper, to cool the brake fluid. Because running flat track or TT, you'll end up boiling the rear brake fluid, loosing the rear brakes, trying to keep from running over them dang slow rolling into the corners 4 pokers.
Most everybody knows on flat track or TT, you run a 2 stroke into a corner wide open & then pitch it sideways to scrub off speed, but when you do, theres a stupid 4 poker in the way & you end up crashed.

So it all boils down to, where Tonys perfection comes into play, with the assorted gussets & brackets he offers to make the best sport quad ever produced, the TRX250R a longer lasting quad.

I'm old, so I just got to lay it out what I know works & what does not, from what my hands have touched, so these kids coming on here might someday remember when I'm gone, yeah, remember ol Neil saying or mentioning that.

This is an awesome addition to the gusset kit. When I installed your kit I was going to Fab up this very rear mount but ended impatient and now looking back I wish I would have Just done it. with this you will Probably need to set the bottom end in to ensure it is in the right place.

Tony, in regards to my recent swing-arm questions... I was thinking maybe I could do the same thing in my situation, but only run the LOWER tabs since my 86 frame doesn't have the upper cross member. This would be a slick quick and dirty way to run an 89 swinger on my 86.

I've considered that, but wasn't sure how that would affect the aluminum swing arm. Also, is the ID the same so I can run an 87 bearing kit? If I had an aluminum one to touch it'd be easier to figure out.

Actually Neil I tap the front brakes just before I go into the turn and pitch it to change my trajectory to miss the slow 4 pokes.....the length of the tap is determined by just how many I want to pass in the turn.....True Story!....
