Progressive springs will help, as will compression dampening. The progressive springs being soft and compliant on the initial stroke of the suspension and then stiffening as they progress into their travel. Compression dampening is present on the BGM dampeners but is a linear rate, hence the more compression dampening you apply to combat the dive, the stiffer and harsh the general ride will feel. Ideally what you need is a multi stage/speed compression dampening to help against braking dive but leave the ride compliant under normal riding. I'm not aware of any front dampeners that have multi stage compression dampening and only one rear shock (PM Tuning's) that has multi stage compression and rebound dampening.

I've got scooters disc fitted on my scoot, I used the weld on bracket, I also made up my own link, like the one pictured earlier, I just bought some male and female rose joints, as the link that came with the kit looked a bit feeble, I am more that happy with this set up, and this will be done to my other scooters, I've got up rated springs and standard dampers fitted, it is well worth doing, if yours turns out anything like mine I'm sure you will be impressed with anti dive, I know I am, I have got some competition brake pads to fit to mine, which will be fitted soon.

I have an LTH anti dive fitted to my RB250 but as it's the only scooter I've ridden with a hydraulic front brake fitted I have nothing to compare it to. The scooter is all legal and ready to go minus a few bits I need to repaint due to a clumsy mate. So as it's not yet on the road is it worth ordering and anti dive kit and fitting it before I get it on the road? Thanks for your comments thus far.

Fitting stiffer springs may help reduce this tendency to dive under braking load but will not cure it and make the front end too hard on bumpy surfaces.
