KTM 690 Enduro/SMC suffer from known and documented problem with weak upper subframe (tank) bolts. This kit minimizes 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. 


  • 2014-On KTM 690 Enduro & SMC
  • All model year Husqvarna 701 Enduro & SMC
  • GasGas 700 - All Years


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 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 then OEM upper tank bolts. 25 mm long, so 15 mm is threaded into the bolt cap, when properly torqued. NOTE: in kits for 2014-on bikes additional button head bolts are provided - those are for Husqvarna 701 bikes. 

Lower assembly:

  • Lower bushings (qty. 2) are made of strong plastic - polyamide with molybdenum, much stronger then OEM rubber lower bushings, yet gentle enough to be in close contact with plastic tank (rubber OEM upper bushings are kept, because completely rigid tank-frame connection wont 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 only difference between kit for 2008-2013 and 2014-on bikes. For 2008-2013 bikes high quality M8x140 allen head 12.9 zinc coated bolt is provided. For 2014-on bikes custom M8x155 countersunk 10.9 zinc coated bolt is provided. 
  • Washers (qty. 1) are standard large M8 steel zinc coated washers andnut(qty. 1) is standard M8 steel zinc coated safety nut.

Complex install

Not that Vanasche can control how KTM designs bikes, but I took a step back when I saw the install instructions. I will probably wait to install until I install the Rade Garage aux tank. Since that requires removing the air box entirely. I wish a bigger surface area air filter (K&N style) was possible, and part of the kit. I hate oiled foam. 5 stars for doing the best they could with the KTM tank tank design. I wonder why the upper rubber bushings are not also replaced with urethane?

Great service, awesome parts!

As I stated, great service and awesome parts. As long as you keep making and selling parts I need, I’ll keep buying from you.

Perun moto subframe bolt kit

Excellent reasonable upgrade. Factory lower subframe bolt it 2 pieces. Upgrade is solid 1 piece bolt. Way better for the subframe support, especially if running rackless bags or duffel on the tail itself
Highly recommend.
