I have now acquired an 8420. A flawed model, and I couldn't resist making some immediate changes.
About this creation
The main image above shows the bike on its new centre stand. The stand in the original model was mounted on the rear swing arm - for a start it was very wobbly and also i've not come across a real bike with a centre stand mounted in this way, so i had to change it to one mounted via the chassis - and whilst i was at it added a kick stand, which a superbike like this is more likely to have than a centre stand anyway; this means that some bulk could be removed from the swingarm, but has resulted in slightly less ground clearance - but then again the rear suspension travel is ludicrously excessive for a bike of this style.



Above, the bike resting on its new kick stand. The kick stand and centre stand will pivot independently without clashing.



Above, the mounting of the stands, which was actually a very simple modification; it is supported at the front and rear underneath the drive shaft and provides very stable support on either stand.



The steering of the original design was appalling, with a pitiful steering lock each way. By removing a few extraneous parts from the stanchions, and raising and widening the handlebars so that they did not clash with the mirrors or the tank, a few extra precious degrees of steering lock have been gained.

The 8420 has great potential for modification, including the weak frame, the bizarre (but impressively smooth) drive train, the rear suspension with too much travel allowing the rear tyre to hit the tail, and the front fork the design of which sadly lacks suspension and causes the front wheel to rub against the fork leg. Next time I have couple of hours to rub together, I might work on this a bit further !

Given the style of this bike, the rear suspension travel does look ludicrous. Not one of Lego's better efforts but your mods are a big improvement. Keep at it!

interesting, very similar to what I have done with my two, although I have removed the centre stand completely and have just the sidestand only.

Quoting Polomoche Mann Brilliant! I like how you find out about real-world bikes and then you tweak the model so its more true to life. It can take a lot of time and patience, but it's always worth it! Great improvements mate!
Thanks very much - I do aim to be as realistic as possible given the limitation of Lego !

Thanks Kenneth, I've just had another look at your versions. I am thinking of extending the front fork length at the top end to allow suspension travel with a mudguard included - as the springs would allow quite a lot of travel anyway, I am guessing it might be the easiest way to retain the mudguard if suspension is added - but would of course mean a rethink of the stands. In addition, the removal of the heavily braced single sided fork should allow a little bit more steering lock to the left. When time allows I will give it all a try ! Although I'm presently at a loss as to how the mudguard could be made to "hug" the tyre as it does in the standard version.
