So which one do you buy?

The Tre-K 899 has the edge if…

Keeping running costs low

Nose ahead: Tre-K 899

The Tre-K 899 should be a little cheaper to keep on the road. It's a small gap.

The 990 Supermoto has the edge if…

Daily commuting & city riding

Edges it: 990 Supermoto

For the ride to work, the 990 Supermoto noses ahead. Put it down to easier maneuvering in tight spots and friendlier manners. Don't let that alone make the call.

Sporty riding on twisty roads

Inches ahead: 990 Supermoto

The 990 Supermoto nudges ahead once the pavement starts to wiggle. It's down to harder acceleration and more feel through the bars. Don't expect a night-and-day difference.

What makes each one tick

Tre-K 899

Behind its tall, upright seat, the Tre-K 899 carries a triple that doesn't come alive until it's spun up. Low down, the engine sags. At corner entry the steel trellis frame drops the bike in at once, and there's no wobble once it's leaned over through the arc. Back on the straight, the front wheel tracks true.

Nils rode the Tre-K 899 in 2009 (NastyNils Testride).

990 Supermoto

There's hardly any bodywork around the upright cockpit, and the 990 Supermoto flicks from lean to lean like a dirt bike. It's already eyeing the next bend. A mid-corner bump disappears into 7.1 in (180 mm) of WP rear travel without knocking the chassis off its line. The LC8 shoves the rear tire out of every bend.
