I see a post from a year ago asking about a motorcycle constructor manual. How is progress?
I posted on your Face Book page and never received an answer from you. I recently received a WOF on my scratch built bike which was registered in 1992, as I have done every 6 months since 2018, but this time was asked for a Modification Declaration. I see on the LTSA website VRIMs that no Mod Dec is cause for failure. I was never offered a Mod Dec when I registered the bike, what is the process now?

I assume from the lack of response to my question that either, A, you do not monitor this page, or B, there has been no progress with any motorcycle constructor's manual?

I assume from the lack of response to my question that either, A, you do not monitor this page, or B, there has been no progress with any motorcycle constructor's manual? Hi You have asked a question in the non-technical part of the forum which LVVTA staff do not regularly monitor. Here is the link for the technical section - lvvta.proboards.com/board/5/technical-talkThere is no motorcycle constructors manual, there is a draft standard out with certifiers but it has not been finalised as yet. A scratchbuilt motorcycle is required to be certified or if the modifications were completed prior to LVV certification coming into force (1st Jan 1992), then a valid declaration will need to be presented to the WoF inspector. In absence of a declaration, a WoF inspector may also accept other authentic evidence to verify that the modifications were completed prior to 1st Jan 1992. Examples of authentic evidence are an invoice from the company that carried out the modification, insurance policy cover notes and motoring magazine features provided they record the vehicle’s registration number or VIN, the modification details and a date or other information verifying when the modifications were carried out. Documents such as statements from previous owners are not acceptable. Without a valid modification declaration or authentic evidence to verify the date of the modifications, it will require certification. Also, if the vehicle has been modified further since 1992, it will require certification to cover those mods. Noting - that if the vehicle has had the registration lapse between the time the modifications were completed (pre 1992) and now, then the declaration and the ability to use the other authentic evidence clause lapses and the bike will require certification.

Hi Chris, Thankyou for your response. Sorry, I posted here in the non-technical part of the forum because I felt that my question was administration rather than technical.  As I built the motorcycle in question, there are no "company records" and the only magazine articles have been written recently, well after the build completion. I have had it authenticated by the VCC as a "Period Special", the bike wears that decal & I guess I will point that out if the question arises again at WOF time. As there is not yet a motorcycle constructors manual & I see no LVVTA standards which appear to be relevant to motorcycles, what do motorcycle certifiers use as a "standard" to certify against? Am I correct in assuming that motorcycle certification is currently completed based on the opinion of a certifier? Ciao, Roy |

Hi Roy, certifiers do have a draft motorcycle standard and formset that they work to that recognises best industry practices.
Regards
Chris

Hi Roy, certifiers do have a draft motorcycle standard and formset that they work to that recognises best industry practices. Regards Chris Thank you again Chris. I see the lack of public access to the motorcycle standard as an impediment to progress. How can constructors work out what is required for their build? In this particular instance, how can I work through the build which I have completed and determine whether it will comply, or not, and whether anything would need to be changed? Currently, I have to accept that it passes or fails based on a certifiers opinion. In the bigger picture, I have had discussions with sidecar owners who have refused my offer of a spare set of professionally produced leading link front forks to improve the steering & safety of their sidecar outfits. Their reason for refusal usually revolves around their fear of "certification" They would rather operate their sidecars with substandard telescopic forks than face the issues, perceived or real, of certification. Questions such as; would professionally made LL forks automatically pass, or would they need to be NDT inspected? How much extra would it cost to have them added to the cert I already have ? What if the certifier doesn't agree with the geometry? etc. If the standard was published, I believe much of this fear could be avoided. Just as a matter of interest, does the draft motorcycle standard contain any of the content which Les Dick, myself, and a third character contributed to back in the '90's, or is it totally new? Regards, Roy |
