Did he say "Hourglass Cycles"? If so, their website says they have closed their doors permanently.

Theyre open @leatal

Thanks for that! Good find.

Interesting larger Delta for TFC HP loss to rear wheel compare to the other three Deltas. No reason for that. (Factory over-quoting TFC HP??)

So ultimate outcome is that the difference on the road is very small and you would wanna be good to pick it?

The map is differnt on the TFC. It has a different exhaust and different valves.

That's good info. Thank you.

Out of curiosity .... we plebs who don't have TFCs seem to be shut out of info re TFC models. As an owner, would you be able to investigate and find out what the valve sizes are?

For comparison, the cooking models are Inlet 37.9 mm (Part No. T.113 0765) and Exhaust 32.3 mm (P/No. T.111 0760.)

Also as a matter of interest, the outside diameter of the final exhaust outlet pipes is 32 mm. What are the TFCs?? Easily measured with a caliper..... that would be a good indication of the differences in the exhaust system.

I’ll measure the exhaust opening but I expect the valve size is the same just made of titanium.

Would be MOST interested to see something in print to this effect......

Maybe this will help.
Print out of dyno for my TFC,
Cheers all,
