X25B RE/Rm.{William Robotham - Chief Engineer}16/KW.8.11.35. Weight Reduction on the Big Bore Chassis. There will be a slight reduction in weight on the big bore chassis. The major weight savings are as follows :- lbs. ozs. Flywheel and clutch 17 0 Propellor Shaft Damper deleted 12 12 Saving on the smaller Dynamo 5 0 Total 34 12 There will be slight additions which we have not yet ascertained due to the larger carburetters and air intake silencer, and an increase of about 2 lbs. due to the cylinder block weight. The nett result will be a saving of about 1/4 cwt. If to this we could add the advantage gained with the steel body, we should be back to our original figure for the Bentley car.
