Well fitting and solid.

The sump guard was easy to fit to my 2009 scrambler. Fixings and guard seem to be good quality and well built. Have only had this product on my bike for a couple of weeks so can not comment on its long term durability. Overall happy with the easy fitment and look.

Great quality & Fit

Black unit, fit to 2010 Bonneville SE mag wheel. Another quality part from TEC. a small parts exploded diagram would be a good addition. The sump guard looks great, does it's job. I didn't realise how peppered my bike was getting until I removed the 4 hole cross member that this bolts to. it was basically sand blasted and needed painting. And on a quick test ride, I could hear the stone pinging on the new sump guard. Looks great too BTW.


Overall good stuff, after install found that it was too close to the oil filter on my 2013 thruxton, had to make 10mm 3d printed bushing/spacer to create the gap between sump and oil filter. that can also be achieved by use multiple washers.

Looks great!

Installed with the help of Dellboy’s garage YouTube vid. It looks great and gives the bike a cleaner look. Highly recommend Tecbikeparts for the low price also.

Pretty good overall. On my SE I noticed that the rear of the plate was tightening against the oil filter (which I didn't think was a particularly good idea) so ended up putting a bit of rubber in between the frame rails and the plate to space it off a bit. I fitted the screws into the rear bracket captive nuts first and locked them off then used the nyloc nuts on the undesired of the plate as this seemed to make it less fiddly to fit.
