looking good john, Recently did some off roading in the peak district, the front end was absolutly brilliant, soaked up some tough stuff with ease


Still got the springs it came with fitted, working quite well for me still.

What's wrong with this picture?



Suspension setup is a bit of a black art to me, so I thought I'd CAD it up to clear my mind. But what it really did was confused me more, because I can't see that this would cause any issues, when people have had some minor clearance issues.

Only thing that I can think of that I ignored is the tyre flattoning. But this would only cause issues with bottom hitting the ground when both front and rear would completely bottom at the same time, AND the tyres flattening at the same time.

Pretty rare it seems to me.

I'm basing all this on the mentioned max. travel figures, and the length of the fork fully extended which I measured. I'd like to keep the fork flush in the clamp which when considering the increased length of preload (due to more travel) should be fine. I've got a Wilbers shock which can increase the rear a fair bit either way.

I made the spacer washer that goes under the top triple 10mm thick . Instant 10 mm bar riser ( if thats high enough for you )

may be ok just want make sure i clear the top of the forks as well.

do you have to change the top brake line as well?

i know the bottom half from calliper is extended but is the line from the abs unit to the actual brake resevoir have to be changed?

You have not considered that the Yamaha forks hold the axle of the front wheel slightly further forward than the OEM forks. That said, I really think that the rear of the bike should be brought up by an 25mm to 35mm to get the balance right. The first thing is to get a 18" rear wheel. Then see how that handles.

The only clearnace issuses I have had so far with my bike have been caused by having to push the forks up throught the yokes by 35mm to quicken up my steering.

The increased offset of the axle would only improve the issue but I actually found that I underestimated the rear suspension travel. It's factory at 210mm. But when you CAD that up the wheel actually goes through the fuel tank.
So something is not right there. Anyway, if you stick to the figures, I reckon I'll limit the travel to 250mm. Which is still a huge improvement the same as the 690E (non R but 275mm that the R has still fits) and more than the Tenere.

I don`t have the numbers . But I still don`t understand why people are mixing in the BMW bearing when both the Yamaha bearings & cups fit .

they are bloddy expensive, got the measurements and no bearing shop sells them as the bike bearing are non standard. the top bearing standard and the bottom bearing runs a non standard ID/OD combination so guess thats why ya ay double price for the bearing kit.
