Frequently Asked Questions
Which bikes does this fit?
Kawasaki KLX400 (2003), Suzuki DR250 (1993–1995), DR350 (1990–1993), DR-Z400E (2000–2007), RM250 (1982–1986), and SG350 Goose (1991–1992). Fitment is based on countershaft/hub fit — verify your exact measurements before ordering, since it can vary within the same model year.
What chain size does this use?
520 pitch.
Are mounting bolts or a lock washer included?
No — this is the sprocket only. Nuts, bolts, and locks are sold separately.
What's it made of?
SCM420 chromoly steel alloy, heat treated and finished to meet or exceed OEM standards.
Do I need to replace the rear sprocket and chain at the same time?
Not required, but a worn chain or rear sprocket paired with a new front sprocket wears out faster — if the rest of your drivetrain is old, it's worth checking before you install just this piece.
