Question for 650 owners

If you upgraded fork with GVE/Intiminator, have you also installed fork brace?

My bike has both a brace and upgraded guts. Mine is a gold valve instead of the imitator My fork is mucho capable and I'm sure you will be pleased with your setup too. To address the question your actually implying...I am blissfully ignorant of how only one upgrade compares to both. You would have to get the opinion of someone who did first one and then the other.

However, the springs are the foundation of your suspension and neither mod will do as much as correct spring rate, but I assume you know this? Once that is sorted, the damping widget of your choice will be able to deliver maximum joy it is capable of.

AS to the brace: the forks are old school skinny and right side up bendy. Fork braces have been used to help this type of flexible fork hold up to the pressure of aggressive braking and square edged impacts since the 70's. You dont see them used on inverted forks but people used to the benefits of their rigidity will definitely appreciate a brace.

I have done GVEs on previous bikes, well aware of their good and bads. And will do either GVE or Intiminators when fork broken in.

While waiting for break in I put brace. And while picking brace off eBay picked used brace for son's bike $30. That bike already had GVE and springs. The brace made that front feel like a completely new bike! Probably as much difference as GVE or more.

Granted it has much thinner fork tubes than Wee, but it is a lighter bike and most of the fork flex comes from seals not tubes.

Now I am tempted to take brace off and do side to side comparison to see how much difference brace made on Wee.

I am also curious if many Wee upgrades (springs, etc) also included brace, and how much of improvements were contributed to (springs, GVE, etc) but were actually due to brace?

Seals do nothing for stiffness. They are rubber after all. It's all in the tubes and bushings. I once put a foot on each side of the front tire of bikes on center stands and wiggled the handlebars with some force. Without a brace, I watched the front fender edge wander across the tire tread. With a brace, not nearly so much. A braced fork provides a much more secure relationship between the handlebars and front wheel direction. The harder you corner, the worse the surface you ride on is and the windier conditions are, the more you benefit from a fork brace,
Lrobby99 and chrisbre like this.

The fork brace is just a good addition that enhances stability.

As GW said, the seals are just rubber rings. The bushing inside the larger fork tube limit side-to-side slop.

The damping valve from any supplier--Race Tech, Ricor, Cogent--is the last step to upgrading the forks. Any of these is a big help, but it isn't the first thing to do.

You need springs to suit your loaded riding weight. Changing the springs does only that. Otherwise, different springs don't improve anything else.

As noted above, the fork brace is important. Get one. Get the correct springs if the stock springs are not right for you (and they're right if you're about 165# or something in that range.)

Stock springs are not an issue for me both Sonic and RT calculators agree they are right for my weight. If they get updated it will likely be last thing on the list and only in case if front turns too soft in relation to rear.


If you look at fork slope comes from all parts of the system: bushings, seals, damping rod... bushings are not only things keeping it in place. While it is debatable how much every part contributes it is obvious fork tubes isn't the only thing which causes it. If it were 43mm fork would have been 21% stiffer than 41mm. Fork brace does nothing to tube flex, it is not even touches them; it reduces amount of seal movement in relation to each other.

I cannot believe how you argue/disagree with people that have been here for a very long time and without question know what they are talking about, but hey do whatever and think whatever makes you feel right.

A fork brace combined with the axle reduces the amount of wheel twist by keeping the #2-26 lower tubes, the fork legs, parallel. You seem to be equating legs with seals. #6-30 is the rubber oil seal and #4-28 is the rubber dust seal. They aren't helping maintain alignment in any manner. Twist is the easiest way for tube flex to deleteriously affect handling. I'm beginning to understand why your screen name is as it is.

I have upgraded internals and a for brace. Love it. I have noticed people come on here looking for advice and then argue that they know better than everyone else. Interweb warriors SHEESH

Whatever you choose to ride, enjoy it and be open to new experiences.
