TT Practice
-----------

During the Isle of Man TT practice in 1928, two fast laps were attempted and it was rumoured that under certain conditions the lower front ends of the swinging\-fork assembly grounded and possibly the centre stand as well. Due to this problem it was not used in the actual race. This story is then contradicted in an article published in the 21 June issue of the Motor Cycle where the failure to complete the two high speed was attributed to a loose exhaust valve lifter affecting the valve operation. The motorcycle was not used in the actual race and was returned to the Birmingham factory. Despite assurances that the journalist apparently received that the model would go straight into production after the TT, this never happened. This could have been due to there being no provision for adjusting the suspension resulting in difficulty in setting the motorcycle up for riders of differing weights nor would it be possible to accommodate pillion loads. More on this later...
