Another historic piece of the CA riding boom leaving. Will be interesting to see what happens.

Joe,

This pic shows how close the CRF Caliper mount is to the TRX Support.....it's off by 1/4"

So, either supply a NEW Steel Support....which I have made out of Stainless.

Or supply a NEW Caliper mount to adapt to the TRX support.

:)
That is really close, especially if it floats center line with the rotor.
Is the leverage ratio the same as the stock caliper too (calculate piston face area)?

It's so close that HONDA should have made it the same size... ;)

The Caliper Pistons are the same diameter, so I would say the lever ratio is the same....it works really good and it's a very clean look.

:D

I haven't done much with R tech, or riding since we focused on our relocation to ID.
That caliper is still used for 2026 bikes. Have you done anything to make this a kit for people to buy? If the leverage ratio is the same, seems like a great solution, given how many stock pistons and calipers are corrosion damaged by now.

I still need to get my cylinder head prototype dome machined and tested - however, my lathe got damaged in the move. At least I have lots of ground to actively test now.

A non conductive anti-seize can help reduce or eliminate the galvanic corrosion.

It's great that someone is putting that kind of effort in!

I don't get that same feeling from a UTV. Maybe one day again... :)

But why would the EPA restrict the making of CORES ? Isn't it just foam ? or Sand with glue ? What is the world coming to ????


Foundry castings still use sand for molds and cores but they mix Sodium Silicate  and Calcium Carbonate into the sand as a binding agent.  CO2 gas is injected into the sand and it hardens the sand making the cores much more durable and less likley to erode or wash out when molten metal is poured into the mold.

Liberal states along the west coast and many other areas of our country are banning this process or requiring foundries to install expensive "scrubbers" to capture the CO2 that their scientist say is destroying our planet.  CO2 is used by plants to live.  Plants give off oxygen that is required for animals and humans to live.  Their scientist have degrees in political science, not degrees in physics and the engineering sciences that actually understand how important CO2 is to the life cycle of our planet.  Our planet is self healing and is constantly readjusting processes to keep everything inbalance. 

Right. The world's most powerful group of people force the climate narrative as a weapon, so it's not a genuine crisis. Once that is understood because you know who the group is, and know what they have done and said over centuries, then it's obvious that climate change, and other chaos creating devices are just tools. The best lies are ones that contain a core of truth. Yes, we should care for our environment, like we care for our personal neighborhoods, etc. That's obvious. But to say that humans being productive, and basically just living is an unsustainable threat to the planet, and needs to be "cleansed", is a lie to facilitate genocidal conquest.

I don't like to be unpleasant in pleasant company on a pleasant site, but this effort to conquer and kill is many generations in the making, and now it's not just our cousins who lived and died in Russia, or Germany for "good" causes, but now the world, and we are past the point of doing anything to stop if people do not talk to each other about the actual perpetrator.

Nice, I imagine a solid amount of work has gone into it!

40 hp is pretty good for such mellow appearing cone design. Revvy engines are the best.
