Riding in the PNW where we acutally use first gear and often gear our bikes down, we tend to use up lots of swingarm guards (the plastic guide that bolts to the swingarm and protects it from the chain). Running a 12T front sprocket on my TM125 resulted in new guards about every 500 miles or so. Anyone know of a more durable brand of guard, maybe like TM designs? I ran the 14/48 combo on my 470 and went thru a couple of guards on it too. I'm hesitant to go to a 15/51 to get a bit of space (and increase slider life), but may have to (the 51T rear puts the rear sprocket more in harms way in ruts).
