THE MIGHTY QUADZILLA

-- SUZUKI'S 500cc MONSTER 2-STROKE QUAD -- Suzuki gets credit for coming out with the first quads as we know them today. First they introduced some little 4-stroke versions and then in 1985 they unleashed a high-performance 2-stroke machine known as the Quadracer 250. Suzuki gave us a couple of years to get used to that great machine and then in 1987 they totally blew us away with a 500cc version. Its official name was the LT500R Quadracer, but it was such a beast that everyone began calling it Quadzilla. You had to be a…

2019 HONDA ATC250R?

-- The latest version of the famous two-stroke three-wheeler -- Ever since Honda dropped their ATC250R after 1986, people have wondered how one would look today if it suddenly returned to the line up. Well, that has not happened yet, but what we have here is probably the closest thing to a 2019 ATC250R that Honda would build. It has an aluminum frame, inverted front forks and a 2-stroke engine with a power-valve, raising and lowering the exhaust port to make a broader power band. So, how did this modern ATC250R come…

THE MIGHTY TIGER 500

-- The fastest 3-wheeler -- What was the fastest 3-wheeler? That distinction has to be the Tiger 500. So, you say you never heard of the Tiger 3-wheeler brand? Well, that's understandable. It wasn't a very large company, but you could buy machines from them between the years of 1983 and 1986. The company was founded by Peter Wood, so the story goes, and the Tiger factory was in Minnesota. The company made their own frames and plastic, and they installed 2-stroke engines from Rotax. The Tiger 500 had the big air-cooled…

CT RACING 400cc BANSHEE

-- 2-stroke power to break the sand barrier -- By the staff of Dirt Wheels, photos by Pat Carrigan CT Racing’s 400cc Banshee kits have been a popular kit for years. CTR originally marketed a 370cc, long-rod kit for the Banshee, but after the 4mm stroker cranks proved dependable, it discontinued the 370cc kit and replaced it with the 400cc kit. They are basically identical kits, but the 400cc kit has a longer stroke. The cylinder bore sizes are the same. The added 4mm of stroke works amazingly on the Banshee. It adds…

THE BEGINNING & END OF HONDA 3-WHEELERS

-- From the US90 to the 250R -- By the staff of Dirt Wheels with Mike Palmgren. A Parrot Green Honda US90 where the ATV world began and the Honda ATC250R that was the end of performance three-wheelers from the company that created them. ATVs survived and thrived, but the 1980s were the troubled end for three-wheelers. As we rolled up to Oceano Dunes SVRA, we were curious where the test subject was hiding. A lot of truly pristine machines roll through Dirt Wheels, but this better-than-new 1970 Honda US90—the very…

1985 YAMAHA TRI-Z 250

-- Not all 3-wheelers were Hondas -- Adam Cook is a Dirt Wheels reader in Ohio. He has owned many quads and a few dirt bikes over the years, but one of his favorite machines in this 1985 Yamaha Tri-Z 250. There's just something about riding a 250cc two-stroke that feels good, no matter how many wheels it has. The engines are simple and easy to work on, and that sudden blast of power is just plain addictive. You quickly learn how to work the shift lever to always keep the revs in the fat part of the power band. This…

BUILDING AN AWESOME BANSHEE

-- Here's a good letter from a Dirt Wheels reader -- Hello Dirt Wheels, My name is Tony Cooper and I wanted to share some before and after pics of my 2003 Yamaha Banshee build.  This is my second submission to Dirt Wheels with my first being a 2011 KFX 450 that made it into your great magazine last year. I bought the Banshee as a project in early 2017.  It was a complete and somewhat running ATV, but it wasn't until I started the tear down that I realized just how much of a project quad I had bought.  The only real…

HONDA TRX250R TEST

-- Built by Lonestar Racing to win! --  By the staff of Dirt Wheels We’ve seen a large number of ATV enthusiasts rebuilding the beloved Honda TRX250R to its former glory. Retro is in right now, and the TRX250R is over 30 years old, so it’s retro for real. For the last decade most TRX250R projects we’ve seen were play machines, but now many riders have started building them to race against modern machinery. The Bosemer family never stopped living the two-stroke lifestyle. You may recall that we featured Rachel…

HONDA 250R MOTOR IN 450R FRAME

-- Don't you wish you could buy this quad from your Honda dealer? They could call it the "30th Anniversary Edition TRX250R". Dirt Wheels reader John Langman didn't wait for Honda to do that -- he built his own. He wanted it to look as close to the original 1986 as possible without too many modifications. John started with a 2005 Honda TRX450R and removed the 4-stroke motor. Next, he fabricated mounts to the frame to install a 1986 Honda TRX250R two-stroke motor. To maintain the original look of the first…

ADAM McGILL’S HONDA TRX250R

-- The Blackwater 100 was dominated by this fast 2-stroke quad -- In 1975 a race was born in the muddy waters of Davis, West Virginia. Dave Coombs, owner of the famed GNCC racing series, was contacted by a small-town preacher in West Virginia regarding the economy of his struggling town. He was interested in hosting a motorcycle race to bring money into the area. Coombs saw the enormous potential, and the Blackwater 100 was born! The Blackwater race was aptly named after nearby Blackwater Falls and Blackwater…
