TRX250R 86 Crankshaft

This is an excellent condition, short rod crankshaft. The designator on the rod is KA4, indicating a CR250R rod. 87-9 crankshafts were 5mm longer, so this shaft will only work with 86 TRX, or CR style pistons. Honda OEM crankshafts for the 250R are discontinued but were the most reliable with the tightest quality control. It's unfortunate Honda no longer makes these. The short rod shafts have been discontinued for about 10 years. DO NOT buy crankshafts from sellers who do not know what the tolerance measurements are. All specs for this crankshaft are within new tolerances.

Specs:

Rod side clearance: .55mm
Runout L: .001"
Runout R: ~.0002"
Radial clearance: ~.0002"
Small end i.d.: .8665"
Shaft bearing race L: 1.1023"
