Forks are more or less stock except progressive springs. We've played with preload spacers and oil weight to get things to work nicely and of course, fork bracing. #280 has a telefix style brace while #91 uses a more "conventional" BMW-style brace plus an additional modified lower triple clamp added a bit further down the legs.

Have you found that the extra lower brace on #91 helps out? Im already running a lower brace as a top.


I am running bt45 100/90-18 front and 120/90-18 but am going to try the am26 90/90-18 and 120/90-18. Kinda want to see how the smaller front tire is going to feel.

I had the BT 45's on my race bike, found them fine. Now running the Avon combo but 19" up front.
Finding the front is getting a real beating.
What they do for me is inspire confidence, that alone is worth the $650 NZ ( $500US) for them.
How do you find the 18" as the Avon guy said to go 18" and wider rim?

One of the faster AHRMA airhead racers runs a BMW rear 18" rim laced to his front hub and Heidenau tires. He says it is the way to go. Hard to argue his success.

Is that the best way to get an 18" front? It will be wider than a normal front rim won't it?

Is the avon guy is a sales man or someone here. My monolever came with 18x2.5 front and back.

Yes, it is wider than a standard front rim. But it works.

Those K65R tires look interesting. I wonder which is smaller: the 110's or a 3.50?

I don't like 19 inch front wheels unless they are on an AMA flat tracker since the rules only allow 19" front and rear. Otherwise I want a 18 on a street bike and 21's on dirt bikes. I guess that's why my beemers have been a R69S, a R65LS, and a R100 Mono. They all have 18" front wheels! GP bikes were 19/19 for decades. Then they were 18/18 for a while and have now mostly been 17/17 for decades now. I like 18/18.

Sure, I am that way with a lot of stuff. Just not motorcycles. And this is a motorcycle forum!

I'm still playing with the pressures on the Avons, on a mid 20's C race meet I started off with 30 front and rear, after race Avon tyre guy was there and said the rear was not working hard enough so less air, and front was working too hard...more air.
ended up with 34 F and 26 R.
19" offers limited tyre choice here, he said your running a Gn250 sized tyre on a large bike.
Saying that the track is 3 km long, 6 turns and only 1 is a left hander.
I should take it to the Taupo meet as it runs anti clockwise to get equal wear
