Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the CHIEF beats 4 of its 4 closest rivals (HARLEY-DAVIDSON FLSTF, HARLEY-DAVIDSON FLSTC, TRIUMPH ROCKET III).

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the CHIEF.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 1946 (98.3% pass). Weakest: 2014 (93.9%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

INDIAN MOTORCYCLE CHIEF FAQ

answers computed from the data above · terms in the glossary

Is the INDIAN MOTORCYCLE CHIEF reliable?

The INDIAN MOTORCYCLE CHIEF is more reliable than average for its class: 93.8% of its 1,096 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #197 of 5426 models.

What does a CHIEF fail its MOT on most?

lamps and reflectors — 26% of all defects recorded against failed CHIEF tests.

What is the best year of CHIEF to buy used?

By first-time pass rate, 2015-registered examples do best (98.3%) and 2014 worst (93.9%). Condition and history still trump the year.

How many miles will a CHIEF last?

The median CHIEF shows 8,000 miles at test, and examples around 20k miles still pass 92.4% of the time — mileage alone rarely kills one.
