Additional Notes

  • The rear differential fluid capacity across the Kawasaki KLF Bayou lineup — covering the 220A, 250A, 300B, 300C, and 400B — is uniformly 0.2 liter, a figure consistent with the compact, single-unit rear differential housings typical of utility ATVs in this displacement class.
  • The front differential on the Bayou 300 4x4, KLF 300C (1995-2004) holds 0.25 liter, a slightly larger capacity than the rear differential on the same machine, reflecting the additional internal components associated with a front drive unit that must also manage axle engagement.
  • The Bayou 400 4x4, KLF 400B front differential capacity changed between production periods. Units from 1993-1994 carry 0.25 liter in the front differential, while the 1994-1999 production period specifies 0.4 liter — a 60 percent increase that points to a revised or enlarged front differential assembly introduced during that model run.
  • Initial service intervals for the KLF 220A rear differential are set at 10 hours of operation, after which the normal change interval shifts to a calendar-based schedule of 1 month. A 1-month normal interval is notably shorter than the 12-month interval specified for all other models in the lineup.
  • The Bayou 250, KLF 250A (2003-2008 and 2009-2011) specifies an initial service change at either 100 km or 10 hours, whichever comes first, for both the front and rear differentials. The dual-trigger format — distance or time — accounts for varying riding conditions where one threshold may be reached well before the other.
  • All 4x4 models — the KLF 300C and both KLF 400B production periods — carry separate front and rear differential fluid specifications, each with independent capacity and interval values. Two-wheel-drive models such as the KLF 220A, 250A, and 300B list only a rear differential entry.
  • The initial service interval of 10 hours, applied across the KLF 300B, 300C, and 400B rear differentials, is intended to flush metal particles generated during the break-in period when new gear surfaces wear against each other. After that first change, the interval extends to 12 months under normal use conditions.
  • The KLF 300B rear differential specifications are divided across three overlapping production periods: 1990-1997, 1997-2001, and 2001-2004. All three share identical capacity and interval values of 0.2 liter and a 12-month normal change interval, with a 10-hour initial service change.
