What Honda Crf450 X failures look like
1,833 Honda Crf450 X tests on record carry the manual reference DVSA attaches to each defect. The most frequent problems were with axles, wheels, tyres and suspension on 487 tests (26.6%), with lamps, reflectors and electrical equipment on 177 tests (9.7%) and with brakes on 163 tests (8.9%). A test can fail on more than one thing, and an MOT can be failed on one defect while another is only advised, so these counts do not add up to the number of tests.
