Using these AS3 Factory Series rear brake pedals and gear levers is straightforward. Just replace your old ones with these new ones on your 2010 - 2017 Honda CRF 250 R. When using the gear lever, the spring - loaded tip helps protect it from damage during impacts, so don't worry too much about hitting it hard. For the brake pedal, the brake snake cable is there to keep it in good shape. As for maintenance, you can clean the levers with a mild soap and water solution regularly. This will help keep the smooth matt anodized finish looking great. Check the tips periodically to make sure they are in good condition. If the brake pedal tip gets worn out, it's replaceable. Remember, this product comes with a 12 - month warranty from the UK company, so if you have any problems, reach out to them.
