SILENCING ENFORCED.

The noise made by motor-cycles on firooklands track has been considerably reduced during the present season. While )t is pity that restrictions of any sort fchould prevail on Britain's only motor fcpeedwav, the motor-cycle movement as a •whole may -juiLo conceivably gain more benefit from there restrictions than it will lose prestige by the handicap they impose bn the would-be record breaker, in the eyes ol! the public the noise of a modern motor-cycle is its worst feature, if it can be demonstrated that a machine can lap Brooklands at, a hundred miles per hour Without, making so much noiso as tho (standard production of another make at 20 m.p.h. on the road, the inevitable result will ho the evolution of much quieter touring machines. The lessons of the track will eventually teach the designer how to intake an engine which will stand up to the throttling effect of an expansion thamber with a comparatively narrow outlet and an even more important effect of Mm restrictions will be to popularise the pi lent sports O.H.V, models. Tho youi){( Ifider has usually in the. past insisted on (silencing arrangements as near to the bpcu exhaust as possible. As a result complaints have lately been made of undue Boise created in our main streets by motorfcyclists passing churches and meeting halls. Those on sick beds also often suffer Acutely in this respect, and if the youthful. enthusiasts could only seo the other Bide of tho question for a moment it is tertuin that, they would forego tho pleasure of tho open cut out or noisy exhaust pi favour of something a little ;more relined and endurable.
