Excerpt from Reports on sports machines of 1926 in the Motor Sport Magazine (penned in 1949).
... a 350-c.c. o.h.c. Chater-Lea combination. The sidecar was of sports pattern, but decidedly heavy and a windscreen and spare wheel were carried, while 3-in. tyres and a full acetylene lighting set were fitted. In addition, wide trials ratios and a rather high-top top were in use, so a speed of over 55 m.p.h. was consideted extremely creditable. In more sporting trim over 65 m.p.h., or 80 m.p.h. solo, was anticipated without tuning. Stanmore Hill was tackled at about 25 m.p.h. in top gear and on 3/4-throttle after the bottom corner the Chater-Lea accelerated steadily, still in top, and went over the summit at about 35 m.p.h.
Later a 53-mile run from one of the University towns was accomplished in 80 minutes with the sidecar heavily-loaded, and no overheating, rattles or discolouration of the exhaust-pipe were evoked. The wide ratios ruined the performance, but 35 m.p.h. was possible in 2nd gear.
The riding position was low and comfortable, the front suspension worked perfectly and steering was at all times light and steady sans damper. Both brakes were really good, but the universal dislike of hand-lever operation of the front one was registered. Absolutely the only criticism of this thoroughbred was that the rear wheel spent rather a lot of its time off the road. The price of the solo was £80."
