Loading...Why my KTM 450 SMR Motorcycle engine won't crank?
If the KTM Motorcycle engine won't crank with the electric starter, it could be due to a few reasons. The battery might be discharged, so try recharging it. A fuse could be blown, in which case you should remove and install the fuse. Alternatively, low external temperatures can be a factor; consider using the 4Ah battery (YTX5L-BS) supplied in the accessories package.
