As we pass the halfway house in the 2017 Kia Twinshock Series Championship, the various championships on both routes are beginning to take shape. The latest round had the riders visiting Hereford and the Platch Farm venue at Ewyas Harold. With an entry of one hundred riders the selection of terrain, which included everything imaginable, produced two very good rides on the Expert route. The organising club had Dan Sanders flying the club flag who parted with just a solitary mark on section one, his only marks of the day. In a two-stroke versus four-stroke battle Andy Hipwell pushed him all the way on his Honda, finishing on two marks lost. On the Clubman route Steve Robson maintained his 100% winning record in all the rounds he has contested on his Fantic, losing just three marks in the process. His nearest challenger, albeit in the Britshock class, was Jim Pickering who parted with seven marks lost on his BSA Bantam.
With the championship attracting strong entries in each of the classes we thought it was time to remind everyone of the entry restrictions for the machines’ eligibility.
Open to all air cooled monoshock and any air cooled monoshock trials motorcycles that have been converted to a twinshock. Eligibility – the motorcycles should maintain the original silhouette as the date of manufacture.

Suitable machines include: Beamish Suzuki, Yamaha TY175 and Honda TL series. These bikes must be completely standard as per original silhouette otherwise enter class three. The object of this class is to keep the cost of competing to a minimum whilst maintaining a highly competitive series. Eligibility – the motorcycles should maintain the original silhouette as the date of manufacture.
