FAQ

This is a widely reported issue on the 790/890 Adventure platform, most often traced to the hose clamp or the housing-to-hose seal rather than a cracked housing itself. Some riders resolve it by simply upgrading to a higher-quality hose clamp; others find the factory hose material itself degrades over time and starts weeping through the layers. If tightening the clamp doesn't fully stop it, replacing the housing and hoses together is the more permanent fix — NICECNC's Thermostat Housing Cover + Silicone Radiator Hose Kit replaces both at once, using a 3-layer reinforced silicone hose designed to resist the layer separation that factory hoses are commonly reported to develop.

If your bike is still under KTM's factory warranty, it's worth taking to a dealer first, since several owners have had this covered as a warranty repair. If you're out of warranty or want to get ahead of it preventatively, the fix itself is straightforward — it doesn't require an engine teardown, mainly access to the hose and housing near the thermostat. NICECNC's silicone hose kit is a common preventative swap for riders who've already had one leak and don't want to deal with it again on a long trip.

This is a known limitation of the stock side stand foot on the 790/890 — it has a small footprint that wasn't really designed for sand, mud, or soft dirt parking. NICECNC's Footstand Enlarger Kickstand Pad bolts directly onto the stock stand and distributes the bike's weight over a larger area; it's a split design (stainless steel upper section, billet aluminum lower section) that adds stability without adding much weight (around 130g), so it doesn't meaningfully change how the stand deploys or feels.

First check whether the master cylinder itself is leaking fluid or just cosmetically scuffed — a scuff alone usually doesn't affect braking, but any fluid seepage means it needs inspection before you ride again. If it's undamaged but exposed, this is a common point of concern for riders who ride off-road regularly, since the rear master cylinder and disc sit fairly exposed on this platform. NICECNC makes a Rear Brake Master Cylinder Guard and a separate Rear Brake Disc Cover/Caliper Guard specifically to prevent this kind of impact damage in the first place, which is worth considering if you plan to keep riding off-road.

Some of that comes down to the OEM shift mechanism's bearing and spring components losing consistency under sustained heat, particularly on long highway stretches or hot-climate rides. NICECNC's High-Performance Pro Shift Kit addresses this with an SKF/NSK hybrid ceramic micro bearing (reduces shifting friction and resists heat buildup) paired with a heat-resistant spring rated to maintain tension in extreme temperatures — it's a direct swap using the stock mounting points (OEM equivalent 63534024000/63634023000).
