DEGENS' 650 DRESDA alternated machine s, Honda and Dre sda , had Hond a not failed mi serably to produ ce some necessary engine parts r equir ed as a result of Nick Mayo' s TT pra ctice crash on 1 June. In fact, I still await th e parts two and a half month s lat er .. . perhap s I should ha ve got a home- built mod el: I could th en hav e hammer ed on the factory door ...

After riding the Dr esd a for 20 laps or so I came to th e con­clu sion that it was about as fast as th e Honda: 7,100-or was it 7,400 ?-a n yway, the gearing char t indi ca ted about 118 m .p. h . as th e b est spee d on th e grandstand straight .. . th e same as tJ1e CB750.

The acce leration was deceptive du e to the la ck of vibrati on a very pleasa nt nov elt y for a verti cal twin in m y hand s. Thank ; ~o t_be Honda I ha ve got very used to ignorin g these subj ectiv e md1 cator s of spee d , and bett er attun ed to simply estimatin g p erforman ce from th e absolut e scale of how fast th e scenery goes past. At mo st point s on the short club circuit th ere was not a lot in it ; the only real point of differ ence was the climb up to Druids Bend, wh ere the Dr esda felt rath er short on steam by CB 750 rating.

Whil e the se are fair compari sons I would · h I . . · · , pomt out l at wa~ not rid~ng ~ y own m achine and so was takin g it good and qw et ly at little if at all under the 70 second s ma k Tl · "Id "d" · r , 115 ml n m g is not a very strin gen t test, to say the least especiall y as I would estimate that_ in good hand s the Dr esda 'should lap at under 59. second s. It 1s not slow, either, and when I found th at th: massive front brake was ju st mildly warm after some deter­mm ed attempts to hea t it up , I was impr essed.

THE RALLY KICK Continued from p agl' 389

Out of th e hairpin ancl on t o the s tart and fini sh s tr a ight, the hoar y R ocket was chuntering pl easan tly into three· figur e spe ed, when th e tr ebl e-lunged Nipponese came alongside; a larg e hand s tret ch ed out ancl cha n ge d into top. Oh, woe, Eng land .

Relativ e po sition s throughout the r est of the tu ss le r ema in e d unchanged, witl1 the Codger in about tw elfth pla ce, though toward th e la s t lap, th e lea din g hun ch seeme d to be drawing in exo rabl y clo se r .

C. H. ruefully opine s that had th e Kawasaki had so m ewh at b ette r ro ad­holdin g and t y r es, h e wou ld ha ve h ad diffi cult y in k eep in g honour s even.

A pres le di ce, the co mp etitor s, or Tather rall y is t s, mill ed in the paddock -comparing experiences, gear r a tio s, tyr es and unp leas ant noi ses from engines .and all the r est of the st rang e co n­glomeration of thin gs that moto r cyc lists compar e. This, how ever, was a rath er diff er ent di sc u ss ion , it b ein g conducted in a weird m e dl ey of Engli sh, Fr ench, .and German th a t would hav e given an interpr e t er ni ghtmar es for life.

Wanderin g off to watch th e suc cess ive heat s, C. H. was pleased to see a BSA Spitfire ridden by a Dutcluunn-no, not the flying gentleman-thoroughly troun ce the 750 c.c. Honda 4 bein g ridden by a bod who obvi ou sly meant bu sine ss [P.A. H. wa s glad, t oo; he' s an un­repentant x enoph ob e.]

Whil e loading-up th e Ro cket for th e return run, C. H. chanced upon an acqua intance fr o m Irel and's Shamro ck Rall y. The pair decid ed to rid e ba ck to Ostcnd together, an opportune dec ision , as lat er events w er e to prov e .

With sc ar ce ly more than 10 miles wid er th e ir belt s, th e pair w er e waved down by the imploring Briti sh owner of a big R oy al Enfield; A clo se inspection suggest ed t hat the co mbin ation of a heavil y -lade n machin e and th e vile B elgian road surfa ce had wrought dele· ter ious effec t s on the RE's r ear wheel b earing s , for the sla ck at th e spindl e was littl e sh ort of hair -rai sing .

After pau se for co11s id era t ion, C. H .'s Ir ish ally load ed all th e RE' s bagga ge into hi s sid eca r , whil e C. H. took on the strand ed pillion passenger. Th e cort cge

th en made it s way to Ostend at a leisur ely cant er. Thi s, says the Codger , wa s all very well , hut hi s pa ssenger was built lik e th e l\1iehelin man, although better fiUed, so th at the Rocket's front wheel only touched down every hundred y ard s or so.

C. H. is now filing a claim for the B elgian mono-wheeling rccord- 120 miles, all told.

Th ey arri ved at Bru gge, 15 miles from the port , well ahead of schedule, and a halt for fodder was agreed upon. How­eve r, so protract ed were the baked meats of this sa turnalia that it was ouly with bar e minutes to spare that the y caught the ferry.

On board, C. H. was approached b y a pl easan t blonde youn g lady, who earnes tl y enquir ed wheth er th ey had been to the Lion Rall y. This was more than a little surprising, for the Belgian event was of r elativ ely minor importance. She explained , however, that a whole half-hour had b een allotted to the Rally on Bel gian television that very afternoon, which h ad included several shots of English machin es and rid ers comp eting in th eir r espective events. It would app ea r th at she had seen th e programm e en tir ely by acciden t in Brusse ls, and had found it so absorbing th at she could no t forb ear makin g further enquiri es.

Thi s revelation so astounded th e Codger that, he assures me, he omitted to ask for h er addr ess, a situati on which, source s inform your scrib e, would , und er normal circum stances, be unthinkabl e !

But, th en, as I said before, motorcyclists do bring out tl1c best in people. P .A. H.
