Once again, we're making you do the work! Every few weeks, we're going to dig into the archives for an old-school photo, and we'll ask you, our knowledgable (???) readers to identify something. Could be the rider, the bike, the track, the year or all four. It will be tough, so if your motocross knowledge only stretches back to Ryan Villopoto's days in the Lites class, you need not apply. 

But if you're sharp, you can win a prize!

Before we get into this week's entry, we will reveal last week's answer and winner.

We asked: Name the rider and the brand of bike he's racing.

The answer: Dave Bickers on a CZ. Congrats to Jim Eckhert of Lakewood, Colorado, for being the first to guess the correct answer. Jim won this sweet t-shirt courtesy of Renthal.

Our friends at Renthal will put a trophy on the line each time, and this week they're giving away a pair of Kevlar Grips to whoever guesses (correctly) first.

Email your answer to Renthal to this address: contests@renthal.com.

Include Racer X Trivia in the subject line, please. By the way, you can bench race all you want in the comments section below but we are not picking winners based on the comments -- you must send the email to be eligible for a prize.

Now, this week's photo: Name the rider and and the brand of bike he's racing. Send the answer to contests@renthal.com and put Racer X Trivia in the subject line. Good luck!
