This epic event will run from February 9, 2025, to February 15, 2025, and is open to bidders in the US or Canada.

This collectible snowmobile will come with a hand-built, custom crate, showcasing the last Sidewinder SRX as it makes its grand appearances at major snowmobile events throughout the season. Don’t miss out on this unique opportunity!

See below for rules and regulations:

1. All bidders must have a credit card on file so we can put a hold on their card for the potential buyer fee.
2. If the card cannot sustain the hold, the bid will not be processed.

Preceding (and living after) the 98/99 SRX 600 – was the SRX 700. The 600 SRX was only a set of de-bored cylinders away from its sibling, the 700 SRX. The basic SRX engine package was the same as the reed valve inducted powerplant used in the Vmax 700 SX triple. The 600 SRX got triple pipes, power valves and a trio of 33mm Mikuni TM series, rack mounted flat slide carbs. The net result is widely accepted as 120 to 125 HP and an indicated 100-plus MPH top end down Kevlar Lake.

SRX always meant lake shredding velocity. However, it had been almost 20 years since Yamaha had hung the moniker on a snowmobile. For the faithful, the stakes were high. Particularly confounding was the absolute dominance (at that time) of the SRX 700. This sled landed with a thunderous impact on the radar run, lake racing snowmobile cognoscenti. The SRX 600? Not so much.

First year SRX 600’s came with a flawed crankshaft – not a small issue – and as a result all 98 SRX 600’s received a new crank early that season. Surprisingly, sales of the 600 SRX did not impress the braintrust at Yamaha and as a result the sled was only offered for two model years, 1998 and 99.

Even though for a 600 class sled the SRX was legitimately potent, the target audience for a no-holds-barred lake weapon is the guy who goes to the top drawer – not one shelf down. Essentially, if you’re going to show up Saturday morning on Kevlar Lake, you come with the biggest gun in the closet or stay home.

Here’s another baffling reality of the 600 SRX. Even though it came with Yamaha’s new trailing arm, equal length radius rod IFS and a full-on double coupled skid, Yamaha elected to shorten up the suspension’s available travel in an effort to improve max lake velocity by lowering the chassis and flattening the arc of the track as it travels around the rear suspension skid. Both are great moves for improving top end, however, the improvement comes at a pretty substantial cost. Namely, ride compliance. Both SRX models were not known for trail riding comfort.

There was an upside to the SRX 600’s lowering and that was exceptional handling on smooth, twisty trails. Suffice it to say lowering the center of gravity on the SRX 600 made for heroic runs through the corners.

The SRX 600 story lives on today with this sled being among a handful of exceptionally desirable snowmobiles. No hardcore Yama-Guru would consider his or her collection of vintage sleds complete without a copy of the very limited production and, as a result, very rare, 98 and/or 99 SRX 600.

Let’s face it, the use-span of a mini-sled only lasts for three or four years and the child outgrows it. It’s frustrating for these future enthusiasts to have to ride on the back of Mom or Pop’s sled when they grow too big for the mini.

The ideal solution was the long-gone Yamaha Sno-Scoot. The used-sled demand for Sno-Scoots makes them as valuable as plutonium. Sno-Scoots and Snow-Sports were precursors of rider-forward orientation and were exactly the right size for junior riders about ten and older.

No, we’re not talking about letting kids that age loose on the snowmobile trails. What we’re saying is there are plenty of applications for sleds this size on private property – even on frozen-safe lakes when parents are supervising.

We also think a lot of kids would love to race sleds that fit them this well and it would give pint-sized racers a place to graduate to before they hit the big leagues (after many years of having to cool their heels because a full-sized sled didn’t fit them).

The best argument for a manufacturer offering an intermediate sled is the way it would cement the kid to a certain brand.

Brand loyalty is one of the most amazing things about snowmobiling and we can’t help but think the younger a child becomes aligned to a certain make, the more they will tend to buy that product when they become an adult.
