Dot demon scrambler

By the late s and early s, DOT was one of dot demon scrambler British companies building competitive two-stroke scramblers. The other companies were Villiers, James, Greeves and Cotton. The DOTs were well designed and well built.

In fact, British rider Bill Baraugh in the early fifties ran his Dot so well against larger machines that the other riders had no choice but to protest that he was riding out of class. More recently, competitors to this small British company caught on and Dot was somewhat eclipsed by machines with engines that put out more frightening amounts of power. Things promise to be different, judging by the prototype of the new cc scrambler to be sold on these shores. Called the Demon, like its predecessors, Dot looks graphically different this year, although this is only a result of its being fitted in fiberglass trappings instead of the familiar alloy. Dot previously employed the Villiers 36A engine, but it had been drawn out to the end of its string in the course of year-in, year-out improvements.

True, the terribly fast Spanish two-strokes are becoming a force to reckon with, but it was the Villiers-powered English machines that first demonstrated that a really light lightweight could beat everything with wheels — and they are still among the best scramblers the world has to offer. Among these English scramblers, all of which seem to have a long-term lease on the winner's circle, one of the best is the Dot Devoid of Trouble , which is much like the others, but manages to have a fairly distinctive flavor of its own anyway. Like its cousins, the Dot is powered by a reworked Villiers engine, in this case the 36A, with a special cylinder and cylinderhead. The cylinder is of aluminum, and has big, long-opening ports — which is roughly the same as having big ports and full-race camshaft in a four-stroke engine. The cylinder head has a completely machined combustion chamber, with a large "squish" area to give controlled combustion at the high compression ratio of Both cylinder and head are heavily finned, and the fins are widely spaced so that they will not clog with mud or dirt and thus cause overheating. Rather than cast an iron liner into this barrel, the makers have elected to simply lay a hard chromium plate in the aluminum bore. This type boie has given problems in the past, with the chrome flaking off near the ports, etc. Also, the cylinder wall's resistance to wear and scuffing has been improved by a new finishing process, in which the cylinder is diamond-lap honed out to the final dimension. This leaves a cross-hatch pattern of fine scratches in the bore, and these scratches tend to hold oil and that vastly improves lubrication. The cross-hatch lapping has of course been regular procedure in iron-liner engines for many years. From all that we could see by an external inspection of the Dot's engine, it did not differ materially from similar gussied-up Villiers, but it certainly had a lot of power.

By the late s and early s, DOT was one of five British companies building competitive two-stroke scramblers. The other companies were Villiers, James, Greeves and Cotton. The DOTs were well designed and well built. The leading-link forks had very long shock dampers and were unique. Compared to competitors like Greeves and Cotton, the DOT was much lighter, and, with the polished aluminum tank and red frame, a lot prettier. Power output was a modest 20 horsepower out of a very loud, open end, blooey pipe that ran under the left side of the engine. The Early Years of Motocross Museum searched high and low for several years to find one, and our featured bike was finally purchased from a collector in Australia. Decades later, the DOT is still a strikingly beautiful machine that almost seems ageless.

The long-travel suspension is certainly instrumental in this, but it also indicates that springs and dampers have been correctly selected. In all truth, we never did learn the proper combination.

The Dot is blessed with one of the more comfortable saddles we have had the pleasure to perch upon, it is wide and soft, with a hard rear edge that tends to hold one's hindside firmly in place when blasting up a hill.

All rights reserved. Only two adverse comments come to mind regarding the engine: first, its stubby megaphone gives off an absolutely ear-drum shattering noise, but this seems to be part and parcel of running a hot two-stroke and there are always ear-plugs ; second, we had a very devil of a time getting it started. Most dry-country riders will probably change to a inch front wheel and a fatter tire, which is better for rocks and sand, while the riders of the Eastern loam may stick with the incher.
