A KTM 990 Supermoto foi lançada em 2008 como uma variante de supermoto legal de rua da plataforma 990 Super Duke/Adventure voltada para a aventura, compartilhando seu motor LC8 V-twin. Ela foi projetada para trazer estilo e manuseio agressivos de supermoto a uma máquina de maior cilindrada, preenchendo a lacuna entre supermotos puramente focadas em pistas e bicicletas de alto desempenho para uso em estradas. A produção continuou até cerca de 2013, quando o foco da KTM mudou para as novas linhas Duke e Adventure, tornando a 990 SM uma máquina relativamente rara e procurada entre os entusiastas de supermotos.

O que os compradores devem saber
LC8 Engine Quirks
The 75-degree V-twin LC8 engine is powerful but known for running hot in slow traffic, often causing discomfort for the rider. Ensure the cooling system and thermostat are in good condition before buying.
Watch the Valve Intervals
Valve clearance checks are required every 6,000 miles and are labor-intensive, making them expensive at a dealership. Always ask for service history to confirm these were not skipped by a previous owner.
Strong Resale Value
The SM 990 holds its value well due to its cult following and limited production numbers, making it a smart buy if purchased at the right price. Low-mileage, well-maintained examples are particularly sought after.

"Loucura de supermoto com capacidade genuína de comer estradas."
O SM 990 pega o lindo gêmeo LC8 do Super Duke e o envolve nas proporções adequadas de supermoto — a altura do assento de 900 mm e as rodas de 17 polegadas fazem com que pareça uma arma afiada no momento em que você se inclina para uma curva. O torque atinge fortemente cerca de 4.500 rpm e absolutamente empurra você para frente em 7.000. Em uma estrada B apertada, isso humilhará as motos esportivas que parecem mais rápidas no papel. Mas conviver com isso é outra história: o gerenciamento de calor é brutal no trânsito, o assento é um dispositivo de punição após duas horas e as primeiras ECUs causam problemas ocasionais de abastecimento que a KTM solucionou discretamente no meio da produção. Não é uma bicicleta de turismo, não está tentando ser, mas nada mais elimina essa coceira em particular.

Avaliação do comprador usado
"A brilliant, high-maintenance lunatic that rewards prepared, attentive owners."
$6,500-$10,500 usedThe SM 990 is the supermoto that rewired my brain about what a big single-cylinder machine could do. That LC8 V-twin pulls hard from nothing and screams past 9,000rpm like it's personally offended by speed limits. It's genuinely fast, absurdly flickable, and sounds absolutely mental. When it's working, nothing touches it for urban aggression or canyon-carving entertainment. Here's the honest part nobody tells you: these bikes eat money when neglected. Check the valve clearances obsessively — they go out of spec and previous owners routinely ignore it. The throttle bodies need syncing, the subframes crack, and KTM's orange paint chips if you breathe near it. Always pull the maintenance history and budget $500-800 immediately for a proper service regardless. Buy one that's been genuinely maintained, not just washed before sale. Find a bike from an enthusiast rather than someone who bought it impulsively and discovered 900cc supermoto wasn't their personality after all. They're out there, and when you find the right one, it's one of the most rewarding bikes you'll ever own.
