Dropping The Front - How Low Can You Go.

[Grey runner]

I have Thunder Ace fork on my FJ they are about 25mm shorter than original FJ forks. Fitted with custom springs and a Wilber shock on the back  I have a quick and light steering bike with plenty of ground clearance to go with my spirited riding.

This thread got me thinking it was about time for me to manufacture some new dog bones.

Having to work last night, I seized the opportunity.

These dog bones are 115mm centre to centre.

Square ends.


End rounding

Have not had a chance to test ride yet and with the lock down, it may be a while.
I do ride the FJ to work every day but, 1km, turn left, 17km, turn left. that's it.
Still, better than nothing.
Looking forward to a decent test ride.

Forgive me for sounding stupid but are those lowering or lifting the rear end?

Not a stupid question.
It can be confusing.

Shortening the dog bones from 125mm to 115mm reduces the clearance between the rear tyre and the road when the bike is on the centre stand.
Therefore, when the rear tyre is on the ground, the rear end of the bike is higher. I know. I was able to place the entire sole of my foot on the road and now I have to stretch.
The dog bones are under tension.

Okay thanks. I didn't know what stock length was. Makes plenty of sense now. Is your rear suspension stock?  I've been looking at doing the f4i shock. Not sure what it does to ride height but from what I read it'll ride and handle better with out spending the money of changing the whole rear end out

The Honda shock dropped the tire raising the back of the bike on the 1350. If you do it. Unless you are really light. You can get a eibach spring 900lbs.. If I remember right. It's the highest rated spring you can put on the Honda shock that still works with the stock valving (according to the Honda forums). Been running one on the 1350. Since I resurrected it. I think I have $170 into it shock,spring, bigger bracket (washer thing) and spring compressor. It's been a long time. So don't remember. It's all in the write up for the shock.

Thanks I remember seeing post about the bigger spring   Pretty easy mod?

The shock I am using is a YSS, MZ456-300TR-29-X.

Spring is probably the easiest part of the mod. Get a good spring compressor. And be careful. Compressed springs can be dangerous.

Haha, anyone who's had one let go knows!

I'll just share this and slowly back out of the room......

That's awesome. But you went the wrong way. Your supposed to go lower in the front and raise the rear

[Pat Conlon]

Kinda opposite of a hard tail.....

An interesting design exercise, might look great on paper, but in building it, the proportions are all jacked.

Hmmmmm, an almost, but not quite. Cover the front end and the back single sided, three spoke set up looks tasty, but that Paris/Dakar sized tank and the scaffold pole forks need slimming. Pretty radical though. The sons of anarchy crowd will love it.
