KTM 690 Enduro R and SMC suffer from known and documented problem with weak upper subframe (tank) bolts. This kit minimizes the chance of failure of upper subframe (tank) bolts, by preventing free play in lower tank joint and by improving quality and design of upper tank joint.
Replacement for weak OEM upper and lower tank bolts.
Available as a kit (upper and lower bolt assembly) for 2008-2019 models.
Please choose the correct year of your bike as there are differences between 2008-2013 and 2014+ models
(Fits on Husqvarna 701) - 701 owners, please read THIS! Button head bolts are now included in the kit.
Upper assembly (bolt caps and bolts) is also available as separate item too, and it is same for all model years.
KTM 690 Enduro and Husqvarna 701 tank bolts issue explained.
Upper assembly:
-
Upper bolt caps (qty. 2) are made of AISI 4140 steel, heat treated (for added strength) then zinc coated (rust protection). That makes them virtually indestructible. Size of the head is standard – 27 mm, same as front axle nut. There is an M6 threaded hole for OEM bolt holding plastic fairing. Bolt cap is designed to be slim, so plastic fairing is not sticking out more then it does when OEM upper bolt is used.
-
Upper bolts (qty. 2 + optional 2) are 12.9 machine bolts, zinc coated. These are much stronger than OEM upper tank bolts. 25 mm long, so 15 mm is threaded into the bolt cap when properly torqued. NOTE: in kits for 2014-2016 bikes additional button head bolts are provided - those are for Husqvarna 701 bikes.
-
M6 small washers (qty. 2) are standard M6 steel zinc coated washers. These are used with OEM M6 bolts, which holds side fairings and bolts into the upper bolt cap.
Lower assembly:
-
Lower bushings (qty. 2) are made of durable plastic - polyamide with molybdenum, much stronger than OEM rubber lower bushings, yet gentle enough to be in close contact with the plastic tank (rubber OEM upper bushings are kept because entirely rigid tank-frame connection won't be a good thing). Slightly different size, so they fit better.
-
Sleeve (qty. 1) is made of AISI 304 stainless steel, without internal thread.
-
Lower bolt (qty. 1) design is the only difference between kit for 2008-2013 and 2014-2016 bikes. For 2008-2013 bikes high quality M8x140 allen head 12.9 zinc coated bolt is provided. For 2014-2016 bikes custom M8x154 mm hex head 10.9 zinc coated bolt is provided.
-
Washers (qty. 1) are standard large M8 steel zinc coated washers, and nut(qty. 1) is standard M8 steel zinc coated safety nut.
