40mm Lowering Kit a G310R

I found a company that makes a suspension lowering kit for a G310R.

It's a bit expensive. I'd go for a rear suspension lowering link that lowers it 25 mm

It is expensive but appears to be for a new shorter shock. If a lowering link comes available, the existing shock would have to be dismantled to change the end of the shock. There is no suspension linkage on the G310R as the shock is connected directly to the top of the swinging arm.

True. Lowering link would be the cheaper. A lower suspension package retains factory ride and ensures better handling. We've done lowering links on other bikes that worked fine. This kit would be more in line with the factory lowered BMW F700GS suspension package. I posted the link to let forum readers know that a lowered suspension package is an alternative to a lowering link.

Yes, I have seen that one and it does involve part dismantling of the shock to swap the parts.

Received the Wilbers 40mm lowering kit from Ted Porter Beemershop. We will get it installed in the next couple of months. We pulled the front springs and rear shock out of the box and we blown away by the quality. We will post an update once have it installed. We are getting SW frame sliders, Akrapovic exhaust, and the lowering kit all at the same time.

I have made a prototype for reducing the overall length of the rear shock. To effectively reduce its length requires replacing the bottom clevis from the shock. To do this safely and easily, I built a shock compressor from some 1" thick plate aluminum and some threaded rods. This allows me to compress and hold the spring while removing the spring retaining washer. The threads on the shock piston rod are M14x1.0mm thread. I have the correct bottoming tap enroute. My test piece I machined from 1018 and 17-4PH stainless can be made even shorter.

I will make another unit from 17-4 for the entire unit including the pivot bushing, and showing the steps to accomplish this task including before and after measurements. When I was looking at the options for the front lower, you get some additional clearance, the bolts holding on the mounting clamps for the handlebars could be replaced with some longer units and add an additional spacer under the clamps. This will raise the bars up, allowing for the front forks to be raised farther upward in the triple tree. Pictures and additional information to follow.

Update to the progress for lowering the rear of the G310R. To help do this change a little safer, I created a spring compressor tool from some 25mm plate aluminum I had on hand along with two 300mm sections of 1/2"-13 threaded rod along with the nuts and washers. I bored out the holes to fit each end of the shock with the deeper pocket to capture the spring.



This tool allows me to safely compress the spring enough to remove the retaining washer from the keeper.





After the retaining washer is removed, you will need a 19mm to loosen the jam nut against the bottom clevis. I was mistaken about the thread pitch prior. It is actually M14x1.25mm. The mounting depth for the factory clevis is 17.5mm deep. Within the photo below are, from left to right: The factory clevis, (47.5mm tall to the center of the bushing), my first prototype (32.5mm tall) and the smallest size (27.0mm tall).



This will reduce the shock overall length to 280.5mm. After measuring the swingarm length, fully extended swingarm position, and adjusting for the shock length, it looks like the shortest version will move the rear axle upward in its arc 59mm. If used in combination with raising the front fork tubes in the triple tree to equal the rear might be a great starting point for my daughter. To get additional clearance under the handlerbars, a set of additional spacers could be made to raise the handlebar clamps. With the factory bolt on each side, there is enough thread to make a 5mm spacer without replacing the M10x65mm bolt with a longer unit.

More to come.
