Hey, Rob

its fine for testing (and riding) to leave unplugged. The abs light stays on on the dash, and the abs doesn't work, but the bike is just fine otherwise.

Its fugly, but a blob of JB weld, or rubber cement with the sensor in it, by the fork guard, seems to work. Just note where the sensor sits on the old fork and try to get a similar angle and distance to your abs/speedo ring.

Got some forks off ebay along with a Tag triple clamp and got the kit to mount everything. Sending the tubes out to HOH next week for Richard to work his magic. I think I am going to have the tubes anodized black too.

Can't wait to get these things on...

Steering stem and fork questions

I sent my forks away to my local suspension shop to get revalved and new springs.

I don't want to shortened the forks (will match that later for the rear shocks) and I will run straight rate springs. The race tech calculator says I need .583 kg/mm rate (200lbs difference between bikes +180 lbs rider weight).

My major concern is that I ran the spring too stiff with .58. Can anyone with a similar setup (no progressive spring) comment on this?


While I was at the shop, I asked about the triple. To my suprise they only charge me $60 dollars to press the stem out of the bottom triple AND machine it down 2mm. It's so cheap , I wonder why everyone here is not doing it!!!??

I'm terrible at doing measurements, so I'm gonna ask again here this question.
If I tune down the bottom diameter of the steering stem, I can use a full BMW bearing kit (2 bears, 2 races, 2 seals) plus the yamaha stem retaining nut. (ok, that's not a question )

The answer re using BMW SH bearings is yes, this is what the people who have done KTM/WP conversions have done

ehatcher & bmacW650, could you weigh the components for a comparison of the different approaches taken with these conversions ?

I have figures for the BMW forks & WP forks but dont have the Yamaha

Would need LHS & RHS fork legs complete, axle & upper & lower yokes

Will post the results for all 3 here if you can provide the information.

+1 on spring rates??? What spring rates are people running? for what rider weight. Will Yamaha Brake lines work on the BMW caliper and mastercylinder?? If not, what length brake line are people using on the front?

the brake line should be a 10mm on both bikes, can't be 100% sure because I'm on WPs (with brembo from ktm).

The issue will be on if its long enough. If you are going from the master on the handlebar, it should reach fine (pay attention to routing). The BMW one will be too short. If you plan on keeping the ABS unit, then the line will be too long (and the BMW one too short).

A new, high quality SS brake line should be no more than $55.

Now, as an aside, does anyone know if the ABS pump puts enough pressure into the system that a stronger line may be needed?

I don't have ABS... and was hoping for someone that has done it, to tell what length to order. I want to have all my parts in hand, so i am not waiting on parts once i begin the project.

The forks, TAG triple, axle and brake adapter weigh 25 pounds.

I am very curious to know what the stock BMW forks, triple and axle weigh.

Or if you don`t turn it down the Yamaha bearings fit . The Yamaha bearings have the exact same bearing cone outer diameter as the BMW bearing cones , the Yamaha bearings fit the Yamaha stem .

Re weight

Figures collected so far are below

BMW Forks, yokes, fork Brace & Axle - 13.4 kgs

KTM Forks, yokes, fork guards & Axle - 11.2 kgs

YZF Forks, yokes, caliper hanger & Axle - 11.4 kgs

These are rough figures so far, a couple of BMW parts to check & the YZF is as per information in the post above, The KTM forks are 4357 not 4860's
The individual part weights, in kg's would assist in more accurate figures.

The KTM & Yamaha forks will feel lighter than the raw figures above as the steel components are all down low giving a lower centre of gravity

On the brake & caliper front, I found today that EBC supply kits to fit KTM & the YZ's with 320mm Discs & the kit includes a caliper hanger for those who want the extra braking power beyond the 300mm BMW disc.
YZ kits are EBC Part No's SM6028C or SM6728C year model dependant

Once you asked, so was I.

The assembly I have sitting here consists of forks, triples (minus the handlebar clamp caps and counter-nut), axle, stock wheel spacer, little plastic shield that I couldn't attach to the new triple, fork brace and brake line clip. My forks are the earlier version without the extra metal around the axle holes.

Total weight according to a hospital scale: 28.5 pounds.
