[QUOTE="Big Sid, post: 39792, member: 2781"] Sid here . When Irving himself built the initial prototype upper frame member he welded in the steering tube but the welding technique at that time caused distortion to creep in on cooling impossible to rectify . That's when he adopted the bolt up assembly employed on Bs and C s . Look closely at the Horner top member and you will see that the steering tube is now welded integral , modern welding allows it now . The main chassis enc the rear swing arm follow closely the original , now mono shock , but all is crafted lighter in modern steels . As the factory would have done . Up front a modern tele fork based upon Kaw . forks carry twin discs , while in the rear a single disc is used . All is done to lighten every piece , necessary to compete with modern machinery especially at the 180 plus mph the 1600 is capable of . They have built a fabulous looking prototype street bike , elect start of course , but Ken feels it would be priced too high to sell on today's market . Even contemplated a SINGLE cylinder version ! Imagine a 90 horse Comet . Not impossible but illogical . [/QUOTE]
