“I don’t trust a bike I can’t see through”

Specifications:
Base – 1648 mm
Rake – 33°
Trail – 148 mm
Clearance – 90 mm
Seat height – 568 mm
Rear tyre – 140/90-15
Front tyre – 90/90-21

The concept
The basic concept for this bike was for an old school design with а clean and stylish look. That’s why I’ve used a hardtail frame and spoked wheels. The latter took me a lot of time to model, but I really like how they turned out in the end. The drivetrain is almost the same as the one used on Primero. I know that a knucklehead or especially a panhead engine would probably suit this kind of overall design much better, but I prefer the more reliable Evo engine. Besides, I don’t have the time and patience to model one of these. The geometry turned out very similar to the geometry of Honda Shadow 1100 Spirit, but the seat height is some 160 mm lower. The final model worked out almost the way I wanted it and I also like how virtually all parts are visible and respectively easy to maintain and replace. I used a lot of parts from the previous CAD bike, so the whole thing took me less than three weeks.

    Cool mix, I’m sure riding such a bike will give enormous pleasure.

    Well, build one and you’ll see. ;)

    Охо, на мен много ми се иска да взема Honda Shadow 750cc и да е моделирам по мой вкус, но за съжаление пари нема. ;)

      Това не бива да ограничава мечтите ти по никакъв начин! Събирай blueprints и всякакви други референции и почвай да моделираш. Ако мога да помогна с нещо, кажи. Аз имам blueprints за моя, а я нета съм мяркал и за още поне 1-2 модела Shadow, единия мисля беше Aero-то :)

    Благодаря за подкрепата.
    Това по никакъв начин не може да ограничи мечтите ми, за това сме хора, да мечтаем.
    Има из нета разни оферти за двигатели, рамки, и други части, та малко по малко, може да се събере мечтата, от тук болче, от там гайка. ;)

      Да, но помисли и за документалната страна на нещата, ако искаш да го караш по пътната мрежа. Аз съм леко скептично настроен към подобно сглобяване на заводски мотоциклет :)

    :)
    Никой не е казал, че ще изглежда заводски.
    Разбира се документите ще са изрядни, инак как ще се регистрира.

    Do you have the cad drawing of just the frame itself? I would be interested to know a little more about the dimensions and see a couple other pictures of just the frame by itself
