Speedway Workshop

TM Junior Speedway Bikes

Young Johnny Ivarsson is 13 years old and can be found riding in 80cc events for Masarna 80cc in Sweden. Johnny has kindly sent in pictures of his TM 85cc machines of which he has two - now there's professionalism for you!!.

I am informed that the TM is an Italian motorcycle factory making Moto X machines ranging from 80cc up to 300cc, this particular motor being the TM 85j MC model.

Good Luck for the future Johnny!....
