So is 171 kg a good bench press?
If that lift is a bench press, 171 kg (378 lb) puts a man at 82.5–87.5 kg bodyweight at the 95th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

135 kg × 9 — common questions
What is my one-rep max if I lift 135 kg for 9 reps?
About 171 kg (378 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 165 to 176 kg, so the range is the honest answer.
Is 171 kg a good bench press?
If the lift is a bench press, 171 kg (378 lb) puts a man at 82.5–87.5 kg bodyweight at the 95th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 69 kg × 5, 94 kg × 5, 120 kg × 3, 137 kg × 2, 154 kg × 1, then the working single at 171 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
