I installed a Roadlok XRA307 onto my V4S today and the following maybe of interest. The OE calliper bolts are 70mm M10 and use 16mm of the 23mm available thread in the fork bracket. Using the recommended 80mm bolt and the E (17.15mm) spacer the bolt only screwed in for 8mm into the thread, the E spacer also brought the Roadlok arm very close / touching the calliper. After some measuring and a very helpful chat with Chris at Roadlok I settled on using the 90mm bolts with the G (19.2mm) spacer and thin washers (also supplied) under the bolt heads. This means that the 90mm bolt uses about 18mm of the 23mm thread, more than enough to hold it securely and the Roadlok arm easily clears the calliper. With this combination the Roadlok works no problem and the pin fits easily into a hole in the disc just as it should, and the retaining bolts (torqued to 45nm) use the same amount of thread (plus 2mm) as the OE bolts. This is important as stated in the Roadlok installation guide. Hope that helps someone install what seems to be a very good product. All I must do now is remember to use it!
If the roadlock is engaged, what stops it being removed by simply taking the calliper bolts out, and giving it a good twist?
Assuming someone is walking around with the right allen key then the Roadlok will still be engaged and act as a normal disc lock and it will be hard to get at the pin that is through the disc. As always if they really want it they will have it! For me its a convenient deterrent, easy to use. always on the bike and only allows a very small movement so no trying to ride off with a disc lock still on the bike!
Great security kit imo. Fitted one to the GS. Only need to carry the pin and key, so ideal for keeping things compact and travelling light. (….I know, ‘light’ on a GS!…)
Exactly. Undoing the bolts holding the roadlok on won't do anything, as it's all held in place by the pin once engaged.
If someone wants to steal your bike they will. This, like any other, is a deterrent or delay tactic rather than prevention.
I agree. I take the layers approach. Despite it being a hassle when securing the bike, the more anti theft devices they have to overcome the more of a deterent it becomes. Of course the brazen professional thief will just hoist your P&J into the back of a van and drive off. Sadly I've been on the receiving end of that. I tend to assess risk and secure accordingly. My Roadlok is a handy part of this being easy to activate and very convenient to carry compared to other disc locks.
Just watching MCN review of bike security options. 8m 20s ... Roadlok: "this is the best disk lock I've ever tested"
Thank you. That saved me a lot of time fitting my Roadlok XRA307 onto my new Multistrada this afternoon. Much appreciated.
Thanks. It looked like the E spacers were fine but were very close to the caliper body. Glad I checked here
Bought nice black stainless bolts from ProBolt after carefully measuring the length requirement for the Roadlok. This means that I only need the one spacer between the calliper and the Roadlok and not extras on the outside to ensure that I have the right length of thread in the fork bottom. On my previous 1260S I used two spacers on each bolt and two of the supplied bolts, the Pike Peak, with it's Ohlins forks, has more of a blind hole in terms of thread depth. So to my mind it's critical to make the most of this by having bolts of the correct length that use as much thread as possible without bottoming out. Added bonus is that the bolt heads don't get manky as easily as the OEM or Roadlok supplied ones. Well, they haven't yet...
Not wishing to be killjoy BUT; are you happy that the tensile strength of the bolts you have ordered are suitable for the job? https://www.bikechatforums.com/viewtopic.php?t=169917
Visited them in person to talk it through. Whilst, granted they're not riding my bike, they were happy with the intended use and said that they'd not had any issues reported. They use 316 A4 stainless. I wouldn't be buying these off of ebay or similar.
