Check your PM , Craig. Just acquired YZ forks to make the conversion. Very excited to make a good bike better with your parts.
@Hansi purchased a kit from me and did his front end As you can see, just too easy. The forks are longer but the difference in travel distance is huge. Ready to go
Thats a great price Craig, my custom job was more but still soooo worth it.I use the yamaha brake hose and route it around the front of the fork like the YZ - it wont get caught on anything that way.
Had a chance to try out the new to me YZ forks with Aquatics conversion parts during a 3 day ride in the high desert of Nevada and Oregon this week. Lots of gravel with washboard, some jeep trails. The Terra feels like a different bike off and on road. Off road the Kayabas soak up the bumps and lumps, always feel planted, hardly a twitch changing directions over any surface. On road the headshake has completely gone, even with the steering damper turned down to the lowest setting. Most dramatic mode I have ever made on a bike. It transformed the Terra into a real dual sport.
I got a message from Mike after they went for a decent ride "Hi Craig, we had the bikes out for a weekend run and I'm happy to report the Husky was superb it feels neutral in the twisties, able to push harder on road, and feels more like my 450 in the bush. We did a mix of fire trails, single track, rocky hill climbs and fast back roads with lots of erosion mound jumps. Handled beautifully, had a ball. Recommend the upgrade. The Spring rate is about 6.5kg though which I initially thought was too stiff but in the rougher conditions at speed worked well" An encouraging statement for anyone sitting on the fence regarding this conversion
The only difference is the 5mm longer. So yes they can be swapped. But.... The husky axle will stick out 5mm on the BMW - No issue The BMW axle will be recessed into the fork by 5mm on a Husky. Not so good. You could still tighten the axle with a thin wall socket. If you stuck in the desert and need to get out. I would do it. But i wouldn't permanently go this way. Black can be done on request Raising links will not work on the Terra because of the way the suspension geometry works. The links need to be shortened by ±9mm to raise the bike 1". But shortening the links by just 2 mm causes interference because the links run horizontal. I am in the process of making a "knuckle"(3 point connector - links, shock and frame) that will raise the rear. I have just sold the last kit and need to make new ones. But I am under that pump doing a production run on another project. Flat out for the next 4 weeks. Bike parts start after that.
Just a quick update Ive been running the 46mm KYBs, Craigs caliper adapter and the standard triple clamp with a custom axle for about 10,000 now No problems with the triples
I'm curious... Does the extra length of the YZ forks cause the front to sit significantly higher when laden with a rider, or does it have more sag that essentially works out to roughly the same geometry as stock? By the way, beautiful looking pieces Aquatic.
yes it would and yes it does. I shortened my travel to 250mm and still have the forks up in the triples to get it handling nice but I will do the rear shock and pick up a bit more travel and height when I get that done. Really depends on the spring you put in there also if you left the originals youd probably have about 3 inches of sag This is not really a cheap conversion if you do the axle, springs and the travel length but man its good
Well, one more bike to modify. I really want to do this to my Terra, and the rear too if the mod parts work out. The price seems perfectly reasonable to me. Now to find someone who can bore the triples, and then find some forks. It may have been posted but can anyone readily post the year(s) to look for on the YZ/WR? Oh, Red! Even though it fades.
The dye Craig, or his machine shop uses is id assume one of the best. I will post pics later of my case saver he did year or so old. Maybe the constant oiling gives it some uv protection?
