Speed Twin Engine Bars

Ooooooh. I need to get the engine protector kit. That’s low volume, but effective stuff.

The head scratching thing is, how do you protect the Speed Twin without ruining the minimalist aesthetic? That’s why I like that engine protector kit.

 

sorry not for me there probably very effective but with me its all about the look of the bike I'll worry about the damage if and when I drop the bike

 

Check your insurance,I stupidly mentioned engine bars on renewal, they wouldn’t insure me ? (CN )?

 

Hi and Greetings.
What Torque settings did you use for the Hepco & Becker frame installation ? Specifically the front 4 (Left and Right side) existing engine to frame mounting points.
Ive noticed Triumph specifies 105Nm on their dresser bars installation which is factory / normal spec for these engine to frame bolts, and that to me seems logical.
Any other aftermarket installation I can find which uses these existing engine to frame mounting points either has no specification for torque settings or a much lower setting (E.g 40Nm for R&G Racing aero sliders).
I can't bring myself to feel comfortable in fitting aftermarket parts using existing load / stress bearing engine to frame mounting points, and then not tightening them back up to factory spec.

So for me it'll be Triumph dresser bars all day long if fitting this type of protector.

Did you come across this yourself?

Thoughts / opinions anyone ?

Thanks

 

That's bonkers! You try to reduce potential damage and therefore cost to the insurance company and they reckon it's a bad thing? I assume CN stands for Carol Nash. If you're looking for a company that actually understands the alterations we make try Bikesure. They list a range of custom changes that make no difference to your premium and you don't even need to notify them, including suspension, exhaust, indicators. Don't know if engine bars are listed but I expect they are.

 

What is the reason that you don't want to tighten to 105nm? Could always get higher spec bolts if the bar kits come with longer ones?

 

When I installed them, I just tightened the frame bolts on my Sato Racing crash bungs to 105 nm. Factory spec, no big deal.

 

Hi Thanks for the reply. Just had a look at the Sato Racing website. First crash / slide protectors I've seen where the existing engine bolts are all re-used other than the Triumph dresser bars . So fully agree no big deal as this, to my mind, would be the logical way forward. Im getting a bit OCD where these quite expensive aftermarket parts replace the original engine bolt / bolts with another type (Lower Spec?) and then either specify a much lower torque setting or non at all. Heres an example. R&G Racing Crash sliders replace the lower engine to frame bolt with a M12 8.8 bolt and then specify no more than 40Nm.
Would it be possible to send a couple of photos of your Sato Racing crash bung installation? I can't find the ones specifically for the Speed Twin on their website. As Triumph have changed the lower engine / frame mounting setup for the Speed Twin (Its different from the Thruxton R) I'd really like to see an actual installation before buying. Info: I recently purchased directly from R&G Racing the Crash sliders marketed for "Thruxton R / Street Twin / Speed Twin". when I looked at the fitting they didn't fit the Speed Twin due to this engine / frame mounting change. After a phone call and refund, R&G have removed the Speed Twin from all marketing for crash sliders. They are currently working on a solution I believe.
Many Thanks and Regards

 

Hi Thanks for the reply. Agree! But thats spending more money after buying these kits. Also I wouldn't really know what spec would be suitable. Material of the said bolts plus loading specs etc. I'm thinking it would have to be something that can be tightened to 105Nm and still have sufficiant remaining strength in the bolt to do its original job (Engine / Frame mounting support).
Have I got this right?
Many Thanks and Regards

 

I guess so, the best option is finding a solution that is able to use the existing bolts or matches the torque. I am no expert on the grading of bolts, was just offering thoughts. I would seek advice from some good suppliers before doing it. I think 12.9 are about the strongest, just don't take the word of this idiot on a forum!

 

Hi, Mops.

Here's a couple of pics of the Sato Racing sliders on my Speed Twin. I also have a latest generation Bonneville with these same sliders.

Frankly, they don't look as stout as the crash bar type that go over the header pipe. But I'm a sucker for the minimal look!

Best

Hi Jet,
Thank you so much for the pics and taking the time to reply. I can see clearly how they are installed on your bike. Again many Thanks and Regards.
Info: Im thinking of dropping the idea of sliders on my bike.
I emailed Saito Racing Yesterday about using the Thruxton R sliders shown on their website as nothing specific shown for the Speed Twin. They replied as follows:
"Thank you for your interest in Sato Racing products!
Our Thruxton-type frame sliders are not compatible with 2019 Speed Twin (different design where the front of the engine attaches to the frame). If we ever start selling frame sliders for the Speed Twin, I will let you know.

Thank you for checking with us!

Regards,

Matt Hall"

What is Matt at Sato Racing smoking? Those same sliders fit on my 2018 Bonneville and 2019 Speed Twin EXACTLY the same way.

The motor mounts for those two bikes and the Thruxton are the same. Where’s my eye roll emoji?

 

I use a setup like this...


1kg = 10N, if spanner is 20cm (i.e. 0.2m) the 1kg reading on scale, is 10N times 0.2m = 2Nm. Just make sure you're pulling at right angles to spanner, If you have C spanners with holes in end, or other means off attaching scales, then you can torque things like head bearings by the book. I do this because every review of any torque wrench I've seen has someone saying the calibration is crap and they stripped threads.
